D. Type in human immune system + HIV effects.
Explanation:
Since Angela is focusing more on the human immune system and the effects of HIV could have on it, the keywords combination that would produce the most relevant search result has to contain human, immune system and HIV effects.
Option A has human, body systems and HIV, immune is absent.
