Assertion: Warm and moist environment can enhance the rate of decomposition
Reason: Warm and moist climate leads to create anaerobic condition which promotes decomposition.

Options

A. If both Assertion and Reason are true and the reason is the correct explanation of the assertion, then mark (1).
B. If both Assertion and Reason are true but the reason is not the correct explanation of the assertion, then mark (2)
C. If Assertion is true but Reason is false, then mark (3).
D. If both Assertion and Reason are false, then mark (4)

Answer

### Step-by-Step Solution:

1. **Understanding the Assertion**: The assertion states that a warm and moist environment can enhance the rate of decomposition. This is true because warm temperatures and moisture levels create favorable conditions for microbial activity, which is essential for decomposition.

2. **Understanding the Reason**: The reason provided claims that a warm and moist climate leads to anaerobic conditions, which promote decomposition. This statement is incorrect. While warm and moist conditions do promote decomposition, they do not create anaerobic conditions. In fact, decomposition is primarily an aerobic process, meaning it requires oxygen.

3. **Analyzing the Relationship**: Since the assertion is true (warm and moist environments enhance decomposition) and the reason is false (it incorrectly states that these conditions create anaerobic environments), we can conclude that the assertion and reason do not support each other.

4. **Conclusion**: The correct answer is that the assertion is true, but the reason is false. Therefore, the answer is option C: Assertion is true, but the reason is false.
