Answer

To solve the question regarding the assertion and reason about heroin, we can break it down into clear steps:

### Step 1: Analyze the Assertion
The assertion states that "Heroin is a CNS depressant."
- **Explanation**: Heroin is indeed classified as a central nervous system (CNS) depressant. This means it slows down brain activity and the functioning of the nervous system, leading to effects such as relaxation and euphoria.

### Step 2: Analyze the Reason
The reason states that "Heroin causes depression."
- **Explanation**: This statement is misleading. While heroin can lead to feelings of euphoria initially, it does not cause clinical depression. Instead, it can lead to a state of sedation and decreased responsiveness in the CNS, which is different from causing depression as a mental health condition.

### Step 3: Determine the Relationship
Now, we need to assess the relationship between the assertion and the reason.
- The assertion is true (heroin is a CNS depressant).
- The reason is false (heroin does not cause depression in the clinical sense).

### Step 4: Choose the Correct Option
Based on the analysis:
- The correct option is that the assertion is true, but the reason is false.

### Final Answer
The correct conclusion is: **Assertion is true, but reason is false.**
