Solution

The correct option is C Helper T-cells
  • AIDS (acquired immunodeficiency syndrome) is caused by the HIV virus.
  • T-helper cells play an important role in adaptive immunity. They not only help activate B cells to secrete antibodies and macrophages to destroy ingested microbes, but they also help activate cytotoxic T cells to kill infected target cells.
  • HIV destroys (CD4+ cells) T-helper cells. They're responsible for keeping us healthy from common diseases and infections. As HIV gradually weakens natural defences, signs and symptoms will occur. Hence AIDS is due to a reduction in the number of helper T-cells. Hence AIDS virus spreads in the body through Helper T-cells.
  • So, the correct answer is 'Helper T-cells'.
