Which of the following best describes compatible?

• A. to go well with something
• B. to make perfect; to complete
• C. to hinder
• D. able to exist in harmony

Answer: (D)

Compatible means two things can exist together without conflict and work well side by side. That makes able to exist in harmony the best description, because it directly expresses the capacity for smooth coexistence and functioning together. Saying something is compatible emphasizes they can operate together without problems. The notion to go well with something is related but often focuses more on fitting or matching in a lighter sense, not the essential ability to function together; to hinder is the opposite, and to make perfect or complete shifts the idea toward perfection rather than compatibility.
