Question

Match List-I with List-II

List-I	List-II
(A) Green power and Bio-fuels	(IV) Vehicle will run on ethanol made from sugar cane and jatropha seeds
(B) Hydro-electric power	(III) Renewable natural resources
(C) Thermal Power	(I) Generated by coal and oil
(D) Nuclear Power	(II) Recent origin and its supply accounts for less than 3% of the total installed capacity of electricity

• (A) - (III), (B) - (I), (C) - (IV), (D) - (II)
• (A) - (II), (B) - (I), (C) - (III), (D) - (IV)
• (A) - (I), (B) - (II), (C) - (IV), (D) - (III)
• (A) - (IV), (B) - (III), (C) - (I), (D) - (II)

Hint:

Categorize power sources into two main groups: \textbf{Renewable} (Hydro, Solar, Wind, Bio-fuels) and \textbf{Non-renewable} (Thermal - Coal/Oil/Gas, Nuclear). This initial classification helps in quickly eliminating incorrect options.

Answer 1

The Correct Option is D

Step 1: Understanding Different Sources of Power:
This question requires matching different types of power generation with their correct description or characteristic.

Step 2: Analyzing and Matching Each Power Source:


(A) Green power and Bio-fuels: Bio-fuels are fuels derived from biomass (plant or algae material or animal waste). Ethanol, produced from sugarcane or jatropha, is a prominent example used to power vehicles. This is a form of green power. This correctly matches with (IV).
(B) Hydro-electric power: This is generated by using the gravitational force of falling or flowing water. Water is a renewable natural resource. This correctly matches with (III).
(C) Thermal Power: This is the most common source of power generation. It is produced by burning fossil fuels like coal, oil, or natural gas to heat water and produce steam, which then drives a turbine. This correctly matches with (I).
(D) Nuclear Power: This uses nuclear fission to generate heat and produce electricity. In India, it is of relatively recent origin compared to hydro and thermal power. As of recent data, its contribution to the total installed capacity is relatively small, typically around 2-3%. This correctly matches with (II).

Step 3: Forming the Correct Combination:
The correct pairings are: A $\rightarrow$ IV, B $\rightarrow$ III, C $\rightarrow$ I, D $\rightarrow$ II.

Step 4: Final Answer:
Looking at the options, option (D) matches our derived sequence.
