When conducting scientific research, appropriate methods must be used to find information that is reliable and valid. Angela was assigned a research project about human body systems for her anatomy course. She would like to focus on the immune system, and more specifically, the effects of HIV on the immune system. Which of the following options would be the best way for her to conduct an online search about her topic?A. Type in human body systems + HIV. B. Type in immune system + human. C. Type in HIV immune system. D. Type in human immune system + HIV effects.

D. Type in human immune system + HIV effects.

Explanation:

Option A has human, body systems and HIV, immune is absent.

Option B contains immune system and human, no HIV effects.

Option C contains HIV and immune system, no human.

All the options are lacking in some ways and will not produce the most relevant search results.
