Reason : Penicillin is a tranquilliser.

Options

A. If both 'A' and 'R' are correct and 'R' is correct reason for 'A'
B. If both 'A' and 'R' are correct and 'R' is not the correct explanation for 'A'
C. If 'A' is true but 'R' is false
D. If both 'A' and 'R' is false

Answer

To solve the question, we need to analyze the assertion and the reason provided:

### Step 1: Analyze the Assertion
The assertion states: "Analgesics bring down the body temperature at high fever."
- **Explanation**: Analgesics are medications that relieve pain but do not necessarily reduce fever. The correct term for medications that reduce fever is "antipyretics." Therefore, this assertion is incorrect.

### Step 2: Analyze the Reason
The reason states: "Penicillin is a tranquilliser."
- **Explanation**: Penicillin is an antibiotic used to treat bacterial infections, not a tranquilliser. Tranquillisers are drugs that affect the central nervous system to reduce anxiety and promote calmness. Therefore, this reason is also incorrect.

### Step 3: Determine the Relationship Between Assertion and Reason
- Since both the assertion and the reason are incorrect, we can conclude that neither statement is true.

### Conclusion
Based on the analysis:
- The assertion is false.
- The reason is false.
- Therefore, the correct answer to the question is that both A and R are false.

### Final Answer
The correct option is D: Both A and R are false.
