Assertion : The honey bee queen copulates only once in her life time.
Reason : The honey bee queen can lay fertilized as well as unfertilized eggs.

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

### Step-by-Step Solution:

1. **Understanding the Assertion**: The assertion states that the honey bee queen copulates only once in her lifetime. This is a well-known fact in entomology, particularly regarding the reproductive behavior of honey bees.

2. **Understanding the Reason**: The reason provided is that the honey bee queen can lay both fertilized and unfertilized eggs. This is also true, as the queen has the ability to control the fertilization of her eggs.

3. **Analyzing the Relationship**: While both the assertion and the reason are true, the reason does not explain why the queen copulates only once. The queen's ability to lay fertilized and unfertilized eggs is a separate fact that does not provide a causal explanation for the assertion.

4. **Conclusion**: Since both statements are true but the reason does not adequately explain the assertion, the correct answer is that both the assertion and reason are true, but the reason is not the correct explanation for the assertion.

### Final Answer:
The correct answer is Option B: Both assertion and reason are true, but the reason is not the correct explanation for the assertion.
