What does AIDS stand for?

• A. Acquired immune deficiency syndrome
• B. Active Immune Disorder Syndrome
• C. Autoimmune Disease Symptom
• D. Acute Immunodeficiency Syndrome

Answer: (A)

The main concept is understanding what AIDS stands for and what it means. AIDS stands for Acquired Immune Deficiency Syndrome. Acquired means the condition isn’t inherited but contracted, usually through infection with HIV. Immune Deficiency means the immune system is weakened and can’t fight infections effectively. Syndrome indicates a group of signs and illnesses that occur together. AIDS is the stage when HIV has severely damaged the immune system, making the body vulnerable to serious infections and certain cancers. This differs from the virus itself (HIV), which is the cause but not yet the advanced stage. The other options aren’t correct because they use terms that don’t match the established meaning of AIDS: they’re not standard or describe autoimmune or acute conditions, whereas AIDS specifically refers to an acquired deficiency that progresses to a syndrome.
