C.

an experimental AIDS vaccine


D.

opportunistic cells that destroy the immune system

Answer 1

The answer is B. immune cells that are destroyed by HIV

CD4+ are immune cells (white blood cells) and are an important part of the immune system. Their name comes from the presence of CD4 glycoprotein on their surface. HIV uses CD4 glycoproteins on the surface of CD4+ cells to entry into the cells. The consequence is a reduced number of those cells. Therefore, CD4+ immune cells are destroyed by HIV.
