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 need to analyze the assertion and the reason given in the statement.

### Step-by-Step Solution:

1. **Identify the Assertion**:
- The assertion states that "Mammals are warm-blooded."
- This is true because mammals, including humans, have the ability to regulate and maintain their body temperature regardless of the external environment.

2. **Identify the Reason**:
- The reason states that "Warm-blooded animals can tolerate only the warm climate."
- This statement is false. Warm-blooded animals (endotherms) can thrive in a range of temperatures, including both warm and cold climates. They have physiological adaptations that allow them to maintain their body temperature in various environmental conditions.

3. **Evaluate the Relationship**:
- Since the assertion is true and the reason is false, we need to determine the correct option based on this evaluation.

4. **Choose the Correct Option**:
- Based on the analysis:
- Option 1 states both assertion and reason are correct, but the reason is not a correct explanation of the assertion. This is incorrect.
- Option 2 states both assertion and reason are correct, but the reason is not a correct explanation of the assertion. This is also incorrect.
- Option 3 states that the assertion is correct and the reason is wrong. This is the correct choice.
- Option 4 states both assertion and reason are wrong. This is incorrect.
- Therefore, the correct answer is Option 3.

### Final Answer:
The correct answer is Option 3: The assertion is correct, and the reason is wrong.
