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

Options

A. Hepatits-A
B. Hepatitis-B
C. Hepatitis-C
D. All of these

Answer

To solve the question, we need to identify which virus among the given options has double-stranded DNA (dsDNA) as its genetic material and is primarily transmitted through sexual contact. Let's break it down step by step.

### Step-by-Step Solution:

1. **Understand the Question**:
- We need to find a virus with dsDNA as genetic material.
- The virus should be transmitted mainly through sexual contact.

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

3. **Identify the Genetic Material**:
- Hepatitis A virus (HAV) has single-stranded RNA (ssRNA) as its genetic material.
- Hepatitis B virus (HBV) has double-stranded DNA (dsDNA) as its genetic material.
- Hepatitis C virus (HCV) has single-stranded RNA (ssRNA) as its genetic material.

4. **Transmission Routes**:
- Hepatitis A is primarily transmitted through the fecal-oral route, not sexual contact.
- Hepatitis B is transmitted through sexual contact, blood, and other body fluids.
- Hepatitis C is mainly transmitted through blood, but also has some sexual transmission risk.

5. **Conclusion**:
- Among the options, only Hepatitis B has dsDNA as its genetic material and is primarily transmitted through sexual contact.
- Therefore, the correct answer is **Hepatitis B**.

### Final Answer:
The virus that has dsDNA as the genetic material and is transmitted mainly by sexual contact is **Hepatitis B**.
