Question

Given below are two statements one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A):
Coal is the world's most abundant fossil fuel that is non-renewable. When and if exhausted, it has to be replaced with other forms of energy. Reason (R):
Energy conservation can reduce energy demands without noticeably changing standard of living. Choose the correct answer from the options given below:

• A. Both (A) and (R) are correct and (R) is the correct explanation of (A)
• B. Both (A) and (R) are correct but (R) is not the correct explanation of (A)
• C. (A) is correct but (R) is not correct
• D. (A) is not correct but (R) is correct

Hint:

Coal is non-renewable because it forms very slowly over millions of years.

Answer 1

The Correct Option is B

Concept:
Coal is a non-renewable energy resource, while energy conservation helps in reducing excessive energy use.

Step 1:
Coal is one of the most abundant fossil fuels and it is non-renewable because it takes millions of years to form. \[ A \text{ is correct} \]

Step 2:
Since coal reserves are limited, they may eventually get exhausted and alternative energy sources will be required.

Step 3:
Energy conservation reduces unnecessary energy consumption without significantly affecting living standards. \[ R \text{ is correct} \]

Step 4:
Although both statements are true, the Reason does not directly explain why coal is non-renewable or why it may get exhausted.

Step 5:
Therefore, both Assertion and Reason are correct, but Reason is not the correct explanation of Assertion. \[ \boxed{\text{(2) Both (A) and (R) are correct but (R) is not the correct explanation of (A)}} \]
