Options

A. If both As and R are correct and R is correct explanation of As
B. If both As and R are correct but R is not correct explanation of As
C. If As is correct, R is wrong
D. If both As and R are wrong.

Answer

To solve the question, we will analyze the assertion and the reason provided, and then determine the relationship between them.

### Step-by-Step Solution:

1. **Identify the Assertion**: The assertion states that the electric ray fish is called "Torpedo".
- **Evaluation**: This statement is correct. The electric ray fish, known scientifically as Torpedo, is capable of producing electricity.

2. **Identify the Reason**: The reason states that dinosaurs are also called "Thunder-Lizards".
- **Evaluation**: This statement is also correct. Dinosaurs are indeed referred to as Thunder-Lizards due to their massive size and the sounds they might have made.

3. **Determine the Relationship**: Now, we need to assess whether the reason provided is a correct explanation of the assertion.
- **Analysis**: While both statements are true, the reason (dinosaurs being called Thunder-Lizards) does not explain why the electric ray fish is called Torpedo. The name "Torpedo" is derived from its ability to generate electric shocks, not from any relation to dinosaurs.

4. **Conclusion**: Both the assertion and the reason are correct, but the reason is not a correct explanation of the assertion.

5. **Select the Correct Option**: Based on the analysis, the correct option is that both the assertion and reason are correct, but the reason is not a correct explanation of the assertion.

### Final Answer:
Both assertion and reason are correct, but the reason is not a correct explanation of the assertion.
