IAF stands for Indian Air Force, but Israel's air force is also acronymed as IAF (Israel Air Force or Heyl Ha'Avir). Other countries like Iceland, Iraq, and Italy have different air force acronyms - Iceland Air Defense Force, Iraqi Air Force, and Aeronautica Militare (Italian Air Force) respectively.

During the 1971 India-Pakistan war, the Indian Navy's INS Vikrant operated Sea Hawks (a type of Hawker Sea Hawk aircraft) which successfully conducted bombing raids on East Pakistan (now Bangladesh). The other options are incorrect: Marut was an Indian Air Force fighter, Harriers were V/STOL aircraft used by other navies, and MiG-29K was inducted much later.

The Tejas Light Combat Aircraft (LCA) Mark 2 will be powered by the General Electric GE-F414 engine, which is more powerful than the GE-F404 used in the current Mark 1 variant. The Kaveri engine project by DRDO faced technical challenges and couldn't meet the required thrust parameters, leading to the selection of the GE-F414 for the upgraded Mark 2 version.

DRDO's Gas Turbine Research Establishment (GTRE) developed the Kaveri engine specifically for India's Light Combat Aircraft (LCA) Tejas program. The Kaveri was an indigenous turbofan engine project aimed at achieving self-reliance in aero-engine technology. While it faced development challenges, it represents India's significant achievement in developing a modern gas turbine engine for fighter aircraft.

The Advanced Light Helicopter (ALH) developed by Hindustan Aeronautics Limited (HAL) is named 'Dhruv'. It's a multi-role utility helicopter designed for both military and civilian operations. Dhruv has been successfully exported to several countries and is known for its versatile performance in various roles including reconnaissance, transport, and medical evacuation.

The Indo-Russian joint project to develop a fifth-generation stealth fighter aircraft for India is called PAK-FA (Perspektivny Aviatsionny Kompleks Frontovoy Aviatsii - Prospective Aviation Complex of Frontal Aviation). India partnered with Russia to co-develop this aircraft based on the Sukhoi T-50 prototype, with the intention of inducting it into the Indian Air Force as FGFA (Fifth Generation Fighter Aircraft).

The Indian Air Force's aerobatic demonstration team is called 'Sarang', which means 'peacock' in Sanskrit. The team performs breathtaking aerial displays using modified HAL Dhruv helicopters. Sarang has represented India at numerous international airshows and showcases the maneuverability of the indigenous Advanced Light Helicopter. (Note: Surya Kiran was the earlier fixed-wing aerobatic team using Kiran aircraft, but that squadron was numbered 52 and later converted to a combat squadron).

Stuxnet was a sophisticated computer worm discovered in 2010 that specifically targeted Iran's nuclear enrichment facilities at Natanz, causing centrifuges to spin out of control and fail. This cyberweapon, widely believed to be a US-Israeli joint operation, significantly delayed Iran's nuclear program by destroying nearly 1,000 centrifuges. The other options (nuira, globalnet, Fox) are not real malware names associated with this incident.

The Morris Worm, created in 1988 by Robert Tappan Morris, is recognized as the first computer worm to spread across the internet. It exploited vulnerabilities in Unix systems and infected approximately 10% of all computers connected to the early internet, making it a pivotal moment in cybersecurity history. The other options (Debris, Dorry, Carry) are fictional names not associated with this incident.

The string 'or'1==1 is a classic SQL injection technique used to bypass authentication. When injected into a poorly constructed SQL query like 'SELECT * FROM users WHERE username=''' + input + '''', it becomes 'SELECT * FROM users WHERE username=''or'1==1' which evaluates to TRUE for all rows, potentially returning all records or bypassing password checks. The key is the single quote structure that closes the username field properly.

Estonia witnessed a massive cyber attack from Russian hackers in 2007, often considered the first instance of state-sponsored cyber warfare against an entire nation. The attack came after Estonia moved a Soviet war memorial, triggering a coordinated distributed denial-of-service (DDoS) assault that targeted government, banking, and media websites, effectively disabling the country's digital infrastructure for weeks. Bulgaria, USA, and China were not the primary targets of this specific incident.

China has been alleged by multiple nations and cybersecurity firms to be behind systematic cyber espionage campaigns targeting high-value systems across government, military, and corporate sectors worldwide. Operations like 'Cloud Hopper' and numerous APT (Advanced Persistent Threat) groups attributed to China have been accused of stealing intellectual property and trade secrets from numerous countries. While Russia and North Korea are also major cyber actors, the question refers to China's broad-based economic espionage campaigns.

Algophobia (from Greek 'algos' meaning pain) is the specific term for abnormal and persistent fear of pain. Agyrophobia is fear of streets, coulrophobia is fear of clowns, and odontophobia is fear of dentists or dental procedures.

Emetophobia (from Greek 'emesis' meaning vomiting) is the specific term for fear of vomiting. Decidophobia is fear of making decisions, keraunophobia and brontophobia both refer to fear of thunder and lightning.

Oikophobia (from Greek 'oikos' meaning house) is the fear of home surroundings, houses, or household appliances. Telephone phobia is fear of telephones, nomophobia is fear of being without a mobile phone, and phagophobia is fear of swallowing.

Cynophobia (from Greek 'kyon' meaning dog) is the fear of dogs. Hydrophobia is fear of water (historically associated with rabies), ichthyophobia is fear of fish, and equinophobia is fear of horses.
