Which term best describes something unfavorable or harmful?

• A. Audible
• B. Adverse
• C. Ambivalent
• D. Apply

Answer: (B)

Adverse describes something unfavorable or harmful. It’s used to signal negative effects, conditions, or outcomes, such as adverse drug reactions or adverse weather, indicating harm or disadvantage. Audible refers to things that can be heard, ambivalent means having mixed feelings or uncertainty, and apply means to put to use or to request. Because adverse specifically conveys a negative impact, it fits the prompt best.
