HIV is the virus that interferes with the body's natural immune system, leading to which condition?

• A. Acquired Immunodeficiency Syndrome
• B. Bacterial Infection
• C. Allergic Reaction
• D. Immunity

Answer: (A)

HIV is a virus that attacks the immune system, especially the CD4 T cells, weakening the body's ability to fight off infections. Over time, as the immune system becomes severely compromised, a late-stage condition called Acquired Immunodeficiency Syndrome develops. AIDS reflects the stage when the immune system is no longer able to defend against many opportunistic infections and certain cancers. So the best answer is Acquired Immunodeficiency Syndrome, because it specifically describes the advanced condition resulting from progressive HIV infection. The other options don’t fit: a bacterial infection is just a type of infection, not the result of HIV; an allergic reaction is an immune system overreaction, not caused by HIV; immunity is the body’s defense, which HIV undermines rather than creates.
