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 snakes and gamma rays, we can break it down step by step:

### Step-by-Step Solution:

1. **Understanding the Assertion**:
- The assertion states that "Snakes exposed to gamma rays become non-poisonous." This implies that exposure to gamma rays has an effect on the toxicity of snakes.

2. **Understanding the Reason**:
- The reason provided is that "Poisonous snakes have poison glands and a pair of fangs. They are affected by gamma rays." This indicates that poisonous snakes possess specific anatomical features and that these features can be influenced by gamma rays.

3. **Analyzing the Assertion**:
- The assertion is indeed true. Research indicates that gamma rays can cause changes in the biochemical structure of the venom, leading to a loss of toxicity.

4. **Analyzing the Reason**:
- The reason is also true. Poisonous snakes do have poison glands and fangs, and they can be affected by gamma rays. However, the reason does not directly explain why exposure to gamma rays makes snakes non-poisonous.

5. **Conclusion**:
- Since both the assertion and reason are true, but the reason does not correctly explain the assertion, the correct answer is (b): If both Assertion and Reason are true, but the Reason is not the correct explanation of the Assertion.

### Final Answer:
(b) If both Assertion and Reason are true, but the Reason is not the correct explanation of the Assertion.
