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.

David Villa is the odd one out because he is a Spanish footballer, while the other three (Beckham, Terry, Figo) are also footballers but from different countries. This question tests pattern recognition across sports personalities. Villa is the only Spanish player among the options.
