Answer

To analyze the given assertion and reason, let's break it down step by step:

### Step-by-Step Solution:

1. **Understanding the Assertion**:
- The assertion states that "Heroin is a CNS depressant."
- CNS stands for Central Nervous System. A CNS depressant is a substance that reduces the activity of the brain and spinal cord, leading to effects such as sedation, relaxation, and decreased anxiety.

2. **Evaluating the Assertion**:
- Heroin is indeed classified as a CNS depressant. It is an opioid that acts on the brain to produce feelings of euphoria and pain relief, but it also slows down brain activity.
- Therefore, the assertion is **true**.

3. **Understanding the Reason**:
- The reason states that "Heroin causes depression."
- While heroin can lead to feelings of sadness or depression in some users, it is primarily known for its pain-relieving and euphoric effects. The term "depression" here can be misleading.

4. **Evaluating the Reason**:
- The term "depression" in this context does not accurately describe the pharmacological effects of heroin. Instead, heroin can lead to a state of euphoria and is often used to alleviate pain.
- Thus, the reason is **false**.

5. **Conclusion**:
- Since the assertion is true and the reason is false, the correct answer is that the assertion is true but the reason is false.

### Final Answer:
- Assertion is true, Reason is false.
