Question

The Human Immunodeficiency Virus causes AIDS by

• A. Depleting $C{D}_4^{+}$ T-helper lymphocytes
• B. Increasing $C{D}_4^{+}$ T-helper lymphocytes
• C. Depleting $C{D}_4^{+}$ T- helper erythrocytes
  
• D. Increasing $C{D}_4^{+}$ T- helper erythrocytes

Answer 1

The correct option is A Depleting $C{D}_4^{+}$ T-helper lymphocytes

HIV causes AIDS by destroying or depleting the number of CD4+ cells or they may functionally impair the cells. This reduces the ability of the immune system to fight against diseases. So, the correct option is 'depleting CD+4 T-helper lymphocytes'.
