HIV selectively targets:

Options

A. B-memory cells
B. T-suppressor cells
C. T-cytotoxic cells
D. T-Helper cells

Answer

**Step-by-Step Solution:**

1. **Understanding HIV**: HIV stands for Human Immunodeficiency Virus. It is a virus that attacks the immune system, specifically targeting certain types of immune cells.

2. **Identifying the Target Cells**: The primary target of HIV is the T helper cells (also known as CD4+ T cells). These cells play a crucial role in the immune response by signaling other immune cells, such as B cells, to produce antibodies.

3. **Impact on Immune Function**: When HIV infects and destroys T helper cells, the immune system's ability to respond to infections is severely compromised. Without T helper cells, B cells cannot be adequately activated to produce antibodies, leading to a weakened immune response.

4. **Differentiating Other Cell Types**: Other types of immune cells, such as B-memory cells, T-suppressor cells, and T-cytotoxic cells, are not the primary targets of HIV. B-memory cells are involved in long-term immunity, T-suppressor cells help regulate the immune response, and T-cytotoxic cells directly kill infected cells.

5. **Conclusion**: Therefore, the correct answer to the question "HIV selectively targets:" is T helper cells.

**Final Answer**: T helper cells.
