Correct answer: B. CD4 T-cells
- A. CD8 T-cells
- B. CD4 T-cells
- C. B - cells

Explanation
HIV gp120 attaches first to the CD4 receptor on helper T lymphocytes, followed by interaction with a chemokine coreceptor such as CCR5 or CXCR4. CD8 cells, B cells and NK cells do not provide the primary receptor for gp120.
