Which phrase does the acronym AIDS represent?

• A. Acquired Immune Deficiency Syndrome
• B. Autoimmune Immune Disorder Syndrome
• C. Acute Immunodeficiency Disorder Syndrome
• D. Acquired Immune Deficit Syndrome

Answer: (A)

AIDS stands for Acquired Immune Deficiency Syndrome. Acquired means the condition develops after birth, not inherited. Immune refers to the immune system, which fights infections. Deficiency means a lack or impairment of immune function. Syndrome indicates a group of signs and symptoms that occur together. The phrase captures the idea of a weakened immune system arising after infection, leading to a set of health problems.

The other options miss the established wording or meaning: autoimmune would imply the immune system attacking the body, which isn’t what AIDS describes; acute suggests a sudden onset and isn’t how the condition is defined; deficit uses a different term than the standard deficiency.
