Answer

To solve the question "Which of these vaccines is not given against viral diseases?", we need to analyze each of the provided options and determine whether they are vaccines for viral or bacterial diseases.

### Step-by-Step Solution:

1. **Identify the Options**: The options given are:
- A) Hepatitis B vaccine
- B) Oral Polio vaccine
- C) MMR (Mumps, Measles, Rubella) vaccine
- D) DPT (Diphtheria, Pertussis, Tetanus) vaccine

2. **Analyze Each Vaccine**:
- **Hepatitis B vaccine**: This vaccine is used to prevent Hepatitis B, which is caused by the Hepatitis B virus. Therefore, this is a viral vaccine.
- **Oral Polio vaccine**: This vaccine is used to prevent poliomyelitis, which is caused by the poliovirus. Hence, this is also a viral vaccine.
- **MMR vaccine**: This vaccine protects against three viral diseases: mumps, measles, and rubella. Therefore, this is a viral vaccine as well.
- **DPT vaccine**: This vaccine is used to prevent three bacterial diseases: Diphtheria, Pertussis (whooping cough), and Tetanus. Since these diseases are caused by bacteria, this vaccine is not against viral diseases.

3. **Conclusion**: Based on the analysis, the vaccine that is not given against viral diseases is the **DPT vaccine**.

### Final Answer:
