Answer 1

The correct option is C The causative HIV retroviruses enters helper T-lymphocytes thus reducing their number.

• 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 lymphocyte cells and reducing their number. They're responsible for keeping you healthy from common diseases and infections. As HIV gradually weakens your natural defences, signs and symptoms will occur.
• Hence HIV attacks T-helper cells.
• So, the correct answer is 'The causative HIV retroviruses enters helper T-lymphocytes thus reducing their number.'.
