C. (c) If Assertion is true statement but Reason is false, then mark c.
D. (d) If both Assertion and Reason are false statements, then mark d.

Answer

To solve the assertion and reason question, we will analyze both statements step by step.

### Step 1: Analyze the Assertion
The assertion states: "LSD and Marijuana are clinically used as analgesics."
- **Explanation**: Analgesics are drugs that relieve pain. LSD (Lysergic Acid Diethylamide) and marijuana (cannabis) are primarily known as hallucinogens, which means they alter perception and can cause hallucinations. While marijuana has been studied for its potential pain-relieving properties, it is not classified as a traditional analgesic like opioids or NSAIDs. Therefore, the assertion is misleading because it suggests a clinical use that is not universally accepted or established.

### Step 2: Analyze the Reason
The reason states: "Both these drugs suppress brain function."
- **Explanation**: This statement is also incorrect. LSD and marijuana are known to be central nervous system stimulants rather than suppressants. They stimulate brain activity and alter perception rather than suppressing it. Thus, the reason does not accurately explain the assertion.

### Step 3: Conclusion
Since both the assertion and the reason are incorrect, we conclude that:
- **Final Answer**: Both assertion and reason are false statements.

### Answer: Option D (Both assertion and reason are false statements)
