HIV stands for which of the following?

• A. Human Immunodeficiency Virus
• B. Human Immunodeficiency Syndrome
• C. Autoimmune Virus
• D. Humoral Immunodeficiency Virus

Answer: (A)

Starting with what the acronym means helps you see what HIV is: a virus that infects humans and weakens the immune system. The word "Human" points to the host; "Immunodeficiency" describes the reduced immune function; and "Virus" identifies the type of pathogen. So the full form is Human Immunodeficiency Virus. This matters because it clarifies that HIV is the pathogen itself, not a disease the body develops. The other options don’t fit: they describe a syndrome (a set of symptoms) or an autoimmune concept (where the immune system attacks the body) or misstate the immune component involved (humoral immunity), whereas HIV specifically targets immune cells and compromises the body's ability to fight infections.
