HIV stands for which term?

• A. Human Immune Deficiency Virus
• B. Hypersensitive Immunodeficiency Virus
• C. Hepatic Immunodeficiency Virus
• D. Human Immunodeficiency Virus

Answer: (D)

The main idea is recognizing what each word in the acronym conveys about the disease. HIV stands for Human Immunodeficiency Virus: human points to the host, immunodeficiency describes a weakened immune system, and virus tells you it’s an infectious agent of the viral family. In medical usage, the correct term is immunodeficiency written as one word, so immune deficiency in two words isn’t the standard form.

The other options mix incorrect terms: hypersensitive isn’t used to describe HIV, hepatic relates to the liver, and none of those phrasings matches the established full form. So the proper full form is Human Immunodeficiency Virus.
