Answer

To answer the question, "In a drunk person, the part of the brain to be affected first is -", we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Question**: We need to identify which part of the brain is affected first when a person consumes alcohol.

2. **Know the Brain Structure**: The brain is divided into several parts, each responsible for different functions:
- **Cerebrum**: Responsible for conscious thought, language, and social interactions.
- **Cerebellum**: Coordinates voluntary movements and balance.
- **Medulla Oblongata**: Controls involuntary functions such as breathing and heart rate.
- **Pons**: Connects different parts of the brain and is involved in regulating sleep and arousal.

3. **Identify Effects of Alcohol**: Alcohol primarily affects the central nervous system. The first noticeable effects of alcohol consumption are on cognitive functions such as judgment, reasoning, and social interactions.

4. **Determine the First Affected Part**: Since the cerebrum is responsible for conscious thoughts, language, and social interactions, it is the first part of the brain to be affected by alcohol. This leads to impaired judgment and altered behavior.

5. **Select the Correct Option**: Based on the understanding that the cerebrum is affected first, we conclude that the correct answer is:
- **Cerebrum (Option D)**.

### Final Answer:
In a drunk person, the part of the brain to be affected first is the **Cerebrum**.
