HIV attacks

Options

A. RBCs
B. blood platelets
C. helper T cells
D. B-cells

Answer

### Step-by-Step Solution:

1. **Understand the Question**: The question asks which type of cell HIV attacks.

2. **Identify HIV**: HIV stands for Human Immunodeficiency Virus. It is important to know what HIV is in order to understand its effects on the body.

3. **Know the Virus Type**: HIV is classified as a retrovirus. This means it has a specific way of replicating within host cells.

4. **Identify Target Cells**: The transcript mentions several types of cells: Red Blood Cells (RBC), Blood Platelets, Helper T Cells, and B Cells. We need to determine which of these cells HIV specifically attacks.

5. **Function of Helper T Cells**: Helper T Cells play a crucial role in the immune system by sending messages regarding pathogens in the body. They are essential for activating other immune cells, including B Cells, which produce antibodies.

6. **Effect of HIV on Helper T Cells**: HIV specifically attacks and deactivates Helper T Cells. This is significant because without active Helper T Cells, the immune response is weakened, leading to increased susceptibility to infections.

7. **Eliminate Other Options**:
- **Red Blood Cells (RBC)**: These cells are responsible for transporting oxygen and do not play a direct role in the immune response.
- **Blood Platelets**: These are involved in blood clotting and do not have a role in fighting infections.
- **B Cells**: While they produce antibodies, their activation depends on the presence of Helper T Cells. If Helper T Cells are deactivated by HIV, B Cells cannot function effectively.

8. **Conclusion**: Based on the information, the correct answer is that HIV attacks Helper T Cells.

### Final Answer:
HIV attacks Helper T Cells.
