Q. AIDS virus destroys
The AIDS virus (HIV - Human Immunodeficiency Virus) primarily targets CD4+ T-lymphocytes (a type of white blood cell). These T-helper cells play a crucial role in the immune system by coordinating the body's response to infections.
When HIV infects and destroys these lymphocytes, the body's immune defense weakens, making it vulnerable to opportunistic infections and diseases, leading to AIDS (Acquired Immunodeficiency Syndrome).
Why not the other options?
- (A) Monocytes → Involved in phagocytosis but not primarily destroyed by HIV.
- (B) Neutrophils → First-line defense cells, not the main target of HIV.
- (C) Basophils → Involved in allergic reactions, not affected by HIV.
Thus, lymphocytes (CD4+ T-cells) are the correct answer!
