(a) If both Assertion and Reason are true and the Reason is the correct explanation of the Assertion.
(b) If both Assertion and Reason are true, but the Reason is not the correct explanation of the Assertion.
(c) If Assertion is true, but Reason is false.

Options

A. If both Assertion and Reason are true and the Reason is the correct explanation of the Assertion.
B. If both Assertion and Reason are true, but the Reason is not the correct explanation of the Assertion.
C. If Assertion is true, but Reason is false.
D. If both Assertion and Reason are false.

Answer

To solve the question regarding the assertion and reason about earthworms, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Assertion**: The assertion states that in earthworms, a developmental larval stage is not found. This is indeed true. Earthworms, specifically the species Lumbricus terrestris (also known as Ferritima), do not undergo a larval stage in their development.

2. **Understand the Reason**: The reason provided is that "because in developmental larval stage is not found." This statement is somewhat redundant and does not provide a valid explanation for the assertion. It merely restates what is already claimed in the assertion.

3. **Evaluate the Truth of Assertion and Reason**:
- The assertion is true: Earthworms do not have a larval stage; they develop directly from fertilized eggs into young worms.
- The reason is false: It does not correctly explain why there is no larval stage; it simply repeats the assertion.

4. **Determine the Correct Option**: Since the assertion is true but the reason is false, the correct answer is (c) If Assertion is true, but Reason is false.

### Final Answer:
(c) If Assertion is true, but Reason is false.
