Which of the following virus has dsDNA as the genetic material and is transmitted mainly be sexual contact ?

Options

A. Hepatitis-A
B. Hepatitis-B
C. Hepatitis-C
D. All of theses

Answer

To solve the question "Which of the following virus has dsDNA as the genetic material and is transmitted mainly by sexual contact?", we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Options**: The options provided are:
- Hepatitis A
- Hepatitis B
- Hepatitis C
- All of these

2. **Analyze Hepatitis A**:
- Hepatitis A is known to contain single-stranded RNA as its genetic material.
- It is primarily transmitted through the fecal-oral route, not sexual contact.

3. **Analyze Hepatitis B**:
- Hepatitis B is known to contain circular double-stranded DNA (dsDNA) as its genetic material.
- It is primarily transmitted through sexual contact, as well as through blood and bodily fluids.

4. **Analyze Hepatitis C**:
- Hepatitis C contains single-stranded RNA as its genetic material.
- It is primarily transmitted through blood, but can also be transmitted sexually, though this is less common compared to Hepatitis B.

5. **Evaluate the Options**:
- Hepatitis A does not have dsDNA and is not transmitted mainly by sexual contact.
- Hepatitis B has dsDNA and is transmitted mainly by sexual contact.
- Hepatitis C does not have dsDNA and is not primarily transmitted sexually.
- The option "All of these" is incorrect since only Hepatitis B fits the criteria.

6. **Conclusion**:
- The correct answer is **Hepatitis B**, as it is the only virus listed that has double-stranded DNA as its genetic material and is transmitted mainly by sexual contact.

### Final Answer:
**Hepatitis B**
