AIDS is caused by HIV that principally infects:

1. all lymphocytes
2. activator B cells
3. cytotoxic T cells
4. T4 lymphocytes

Correct answer: T4 lymphocytes

Solution

HIV primarily binds to CD4 receptors, so it infects T4 (helper) lymphocytes. These cells coordinate immune responses, and their loss leads to the immunodeficiency seen in AIDS.
