Indian Geography and General Science Quiz

To solve this question, the user needs to know about the history of Washington D.C. and the meaning of its name.

The correct answer is:

B. District of Columbia

Explanation:

Washington D.C. is the capital city of the United States of America. The city was named after George Washington, the first President of the United States, and Christopher Columbus, the explorer who discovered the New World. "D.C." stands for "District of Columbia," which is a federal district that serves as the capital of the United States. The district was created in 1790 by the U.S. Congress as a result of the Residence Act, which designated a permanent capital for the country. Therefore, option B is the correct answer.

Option A is incorrect because there is no such thing as the Directorate of Columbus.

Option C is incorrect because "Democratic Columbia" is not a term used to describe Washington D.C.

Option D is incorrect because the correct term is "District of Columbia," not "District of Columbus."

South Africa is the only country with three official capitals: Pretoria (executive), Cape Town (legislative), and Bloemfontein (judicial). This unique arrangement reflects the political compromise during the formation of the Union of South Africa in 1910.

Rajasthan is the largest state in India by area, covering approximately 342,239 square kilometers (about 10.4% of India's total geographical area). Uttar Pradesh is the most populous, while Madhya Pradesh was previously the largest before reorganization.

The Eastern Ghats are characterized by discontinuous low hills, with the Mahendragiri hills being a prominent feature. The Nilgiris are part of the Western Ghats, while Sahyadri is another name for the Western Ghats range. 'Narendra giri' appears to be a fabricated option.

Silver nitrate (AgNO3) is used in indelible election ink because it reacts with the keratin in skin and fingernails to form silver argentate, which cannot be washed off and remains visible for several days. The purple stain is difficult to remove and prevents duplicate voting.

The Constitution of the Islamic Republic of Iran designates Twelver Shia Islam as the official state religion. While 'Islam' is the broader faith, the specific branch recognized by the state is Shia, distinguishing it from Sunni Islam or the ancient Zoroastrian faith.

Sodium chloride (NaCl) is the chemical name for common table salt. While the other options are technically chemical salts (nitrates and potassium salts), NaCl is the specific substance referred to as 'salt' in a general or culinary context.

Calcium carbonate (CaCO3) is the main chemical compound that provides the rigid structure of bird eggshells. The other options represent different calcium salts like chloride, nitrate, or sulfate, which do not constitute the shell material.

Eggshells are primarily composed of calcium carbonate (CaCO3), which makes up about 95% of the shell's structure. CaCl (calcium chloride), CaNo3 (calcium nitrate), and CaSO4 (calcium sulfate) are different salts not found as the primary structural component of eggshells.

Carbonic acid (H2CO3) is formed when carbon dioxide is dissolved in water under pressure, creating the characteristic fizz in soft drinks. HCL and H2SO4 are strong, corrosive mineral acids, and H2No3 is an incorrect chemical formula for nitric acid (HNO3).

The Deccan Plateau is bounded by the Satpura Range in the north and extends to Kanyakumari at India's southern tip. The Nilgiri Hills are part of the Western Ghats but do not mark the southern boundary of the plateau.

Ravi and Beas are two of the five major eastern tributaries of the Indus River system in the Punjab region. Gangotri is a glacier and the source of the Ganges, while Sindh is a province in Pakistan through which the Indus flows, not a tributary itself.

Water consists of two hydrogen atoms bonded to one oxygen atom, giving it the chemical formula H2O. CO2 is carbon dioxide, NO2 is nitrogen dioxide, and CaO is calcium oxide.

Aksai Chin (misspelled as 'Askai Chin') is the China-administered territory that India claims as part of Ladakh. Azad Kashmir is Pakistan-administered Kashmir. 'Tsampa' is a Tibetan food, unrelated to this territorial dispute.

While India has hundreds of languages, the number of distinct writing scripts used for major languages is approximately 25. This reflects the diverse linguistic and orthographic heritage of the subcontinent.

Compressed Natural Gas (CNG) is primarily composed of Methane (CH4), which typically makes up 70% to 90% of the mixture, along with small amounts of ethane and other gases.

This question is grammatically incomplete but likely refers to the second most spoken language in India. Hindi is first, Bengali is second. Telugu and Marathi have fewer speakers. The question should specify context (India or worldwide).
