Which of the following is correct regarding AIDS causative agent HIV

Options

A. HIV is enveloped virus containing one molecules of single-stranded RNA and one molecule of reverse transcriptase.
B. HIV is enveloped virus that contains two identical molecule of single stranded RNA and two molecules of reverse transcriptase.
C. HIV is unenveloped tetrovirus
D. HIV does not escape but attacks the acquried immune response.

Answer

To determine which statement is correct regarding the causative agent of AIDS, HIV, we need to analyze the options provided based on the structure and characteristics of the virus.

### Step-by-Step Solution:

1. **Understanding HIV**:
- HIV stands for Human Immunodeficiency Virus, which is the virus responsible for causing Acquired Immunodeficiency Syndrome (AIDS). It primarily attacks the immune system, weakening the body's ability to fight infections.

2. **Analyzing the Options**:
- **Option 1**: "HIV is an enveloped virus containing one molecule of single-stranded RNA and one molecule of reverse transcriptase."
- This statement is incorrect because HIV contains two molecules of RNA, not one.

- **Option 2**: "HIV is an enveloped virus that contains two identical molecules of single-stranded RNA and two molecules of reverse transcriptase."
- This statement is correct. HIV is indeed an enveloped virus with two identical single-stranded RNA molecules and two reverse transcriptase enzymes.

- **Option 3**: "HIV is an unenveloped retrovirus."
- This statement is incorrect because HIV is an enveloped virus, not unenveloped.

- **Option 4**: "HIV does not escape but attacks the acquired immune system immune response."
- While HIV does attack the immune system, the phrasing is misleading. It suggests that HIV does not leave the body, which is not accurate.

3. **Conclusion**:
- Based on the analysis of the options, the correct statement regarding HIV is **Option 2**: "HIV is an enveloped virus that contains two identical molecules of single-stranded RNA and two molecules of reverse transcriptase."

### Final Answer:
The correct option is: **HIV is an enveloped virus that contains two identical molecules of single-stranded RNA and two molecules of reverse transcriptase.**
