Explanation:

• Option A: Opportunistic infections (OIs) target people with weakened immune systems (like those with HIV/AIDS), not healthy ones. Eliminate A.
• Option B: OIs are more frequent in later stages of HIV when the immune system is severely compromised, not earlier. Eliminate B.
• Option C: In people with HIV/AIDS, as the immune system declines, OIs become common and are a leading cause of death. This matches the definition of OIs.
• Option D: OIs rarely affect perfectly healthy people since their immune systems can fight off the pathogens causing OIs. Eliminate D.

Answer:

C. OIs are the common cause of death of people with HIV/AIDS.
