They help the activity of other immune cells by releasing T cell cytokines. When the HIV infects the man it enters into the T-helper cells for replication and they utilize metabolic mechanism from T- helper cells. By the viral replication, T-helper cells get damaged and their number is gradually reduced.

So, the correct answer is 'T-helper cells only'
