Assertion. Snakes exposed to gamma rays become non- poisonous. Reason. Poisonous snakes have poison glands and a pair of fangs.
They are affected by gamma rays.

Options

A. if both are ture with reason being correct explaination
B. both true but reason not correct explanation
C. assertion true but reason wrong
D. and both wrong

Answer

### 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. **Analyzing the Reason**: The reason given is that "poisonous snakes have poison glands and a pair of fangs, and they are affected by gamma rays." This statement describes the anatomical features of poisonous snakes and suggests that these features are influenced by gamma rays.

3. **Evaluating the Assertion**: Gamma rays are high-energy radiations that can penetrate living tissues. When snakes are exposed to gamma rays, the radiation can cause conformational changes in the proteins that make up their venom. This results in a loss of toxicity, making the snakes effectively non-poisonous.

4. **Evaluating the Reason**: While it is true that poisonous snakes have poison glands and fangs, the reason does not adequately explain why exposure to gamma rays would make them non-poisonous. The assertion focuses on the effect of gamma rays on venom toxicity, while the reason merely states the anatomical features of poisonous snakes.

5. **Conclusion**: Both the assertion and the reason are true statements. However, the reason does not provide a correct explanation for the assertion. Therefore, the correct conclusion is that both statements are true, but the reason is not the correct explanation for the assertion.

### Final Answer:
Both statements are true, but the reason is not the correct explanation.
