C. Megaloblastic anemia
D. Yellow fever

Answer

To solve the question regarding the most common cause of jaundice produced by a DNA virus, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Jaundice**:
- Jaundice is a condition characterized by yellowing of the skin and eyes due to an increase in bilirubin levels in the blood. This occurs when the liver is unable to filter out bilirubin effectively.

2. **Identifying the Options**:
- The options provided are:
- A) Hepatitis B
- B) Hepatitis A
- C) Megaloblastic anemia
- D) Yellow fever

3. **Analyzing Each Option**:
- **Option A: Hepatitis B**:
- Caused by the Hepatitis B virus, which is a partially double-stranded DNA virus. This virus can lead to jaundice.
- **Option B: Hepatitis A**:
- Caused by the Hepatitis A virus, which is an RNA virus, not a DNA virus. It can cause jaundice but does not fit the criteria of being a DNA virus.
- **Option C: Megaloblastic anemia**:
- This is a condition characterized by the presence of large, abnormal red blood cells and is not caused by a virus. It does not lead to jaundice directly.
- **Option D: Yellow fever**:
- Caused by a virus transmitted by mosquitoes, specifically an RNA virus. It can cause jaundice but is not a DNA virus.

4. **Conclusion**:
- Among the options, Hepatitis B is the only one that is caused by a DNA virus and can lead to jaundice. Therefore, the correct answer is **Option A: Hepatitis B**.

### Final Answer:
The most common cause of jaundice which is produced by a DNA virus is **Hepatitis B**.
