Question Details

Given below are two statements: one is labeled as assertion (A) and the other is labeled as

reason(R)

Assertion (A): Energy produced from biomass is considered 'carbon neutral".

Reason (R): Biomass does not add CO2 to the atmosphere.

In the light of the above statements, choose the most appropriate answer from the options given below:

Options

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

Show Answer

Correct Answer :

Option C

(A) is correct but (R) is not correct

Solution :

The correct answer is (A) is correct but (R) is not correct.

Step-by-step Explanation:

1. Analysis of Assertion (A):
Assertion (A) states: "Energy produced from biomass is considered 'carbon neutral'."
Biomass energy (bioenergy) is generated from organic materials such as plants, wood, and agricultural waste. During their growth cycle, plants absorb carbon dioxide (CO2) from the atmosphere through the process of photosynthesis. When this biomass is later burned or converted to produce energy, it releases that stored CO2 back into the atmosphere. Because the carbon released during combustion is roughly equivalent to the carbon absorbed during the plant's lifetime, the overall lifecycle carbon footprint of biomass energy is theoretically balanced, making it "carbon neutral". Therefore, Assertion (A) is correct.

2. Analysis of Reason (R):
Reason (R) states: "Biomass does not add CO2 to the atmosphere."
This statement is factually incorrect. The combustion or decomposition of biomass directly releases carbon dioxide (CO2) into the atmosphere. The carbon neutrality of biomass does not mean it avoids emitting CO2 altogether; rather, it means the emitted CO2 is offset by the carbon captured during the growth phase of the organic matter. Since biomass combustion does add CO2 to the atmosphere, Reason (R) is not correct.

Conclusion:
Since Assertion (A) is correct and Reason (R) is not correct, the most appropriate option is "(A) is correct but (R) is not correct".
