correct explanation of the Assertion.
C. If Assertion is true, but Reason is false.
D. If both Assertion and Reason are false.

Answer

### Step-by-Step Solution:

1. **Understanding the Assertion**: The assertion states that "Earthworm is saprozoic."
- **Explanation**: Saprozoic organisms are those that feed on dead and decaying organic matter. Earthworms are known to consume organic matter in the soil, which includes decomposing plant material and other organic debris.

2. **Understanding the Reason**: The reason given is "Because it feeds on small insects."
- **Explanation**: This statement is misleading. Earthworms primarily feed on organic matter, not small insects. They do not have a diet that includes living insects, which would classify them as insectivorous organisms.

3. **Evaluating the Truth of the Assertion and Reason**:
- The assertion is **true** because earthworms are indeed saprozoic.
- The reason is **false** because earthworms do not feed on small insects; they feed on decomposing organic matter.

4. **Conclusion**: Based on the evaluation, the correct answer is that the assertion is true and the reason is false. Therefore, the answer is C.
