Question

Assertion (A): Carbon and its compounds are our major sources of fuels.
Reason (R): Most of the carbon compounds on burning release a large amount of heat and light.

• A. Both Assertion (A) and Reason (R) are true and Reason (R) is the correct explanation of Assertion (A).
• B. Both Assertion (A) and Reason (R) are true, and Reason (R) is not the correct explanation of Assertion (A).
• C. Assertion (A) is true, but Reason (R) is false.
• D. Assertion (A) is false, but Reason (R) is true.

Hint:

Burning carbon compounds like coal and oil releases energy in the form of heat and light, which is why they are used as fuel sources.

Answer 1

The Correct Option is A

Carbon and its compounds, such as coal, petroleum, and natural gas, are indeed major sources of fuel.
When these carbon compounds burn, they release a significant amount of energy in the form of heat and light, which is why they are used as fuels. Thus, both Assertion (A) and Reason (R) are true, and Reason (R) explains Assertion (A).
