HIV responsible for AIDS in human is a:

Options

A. ssDNA virus
B. dsDNA virus
C. ssRNA virus
D. dsRNA virus

Answer

To answer the question "HIV responsible for AIDS in humans is a:", we need to analyze the characteristics of the HIV virus.

### Step-by-Step Solution:

1. **Identify the Virus**: Start by recognizing that HIV stands for Human Immunodeficiency Virus, which is known to cause AIDS (Acquired Immunodeficiency Syndrome).

2. **Determine the Virus Family**: HIV belongs to the family of Retroviridae and is classified under the genus Lentivirus.

3. **Examine the Structure of HIV**: HIV is characterized as an enveloped virus. This means it has a lipid membrane surrounding its genetic material.

4. **Identify the Genetic Material**: The genetic material of HIV is RNA. Specifically, it is a single-stranded RNA virus.

5. **Replication Process**: Once inside the host cell, HIV converts its single-stranded RNA into double-stranded DNA through a process called reverse transcription. This is a key feature of retroviruses.

6. **Conclusion**: Based on the above characteristics, we can conclude that HIV is a single-stranded RNA virus.

### Final Answer:
HIV responsible for AIDS in humans is a **single-stranded RNA virus**.
