Which option best defines complement?

• A. to go well with something
• B. to make perfect; to complete
• C. to hinder
• D. to replace

Answer: (A)

Complement is about two things fitting together or enhancing each other. The best choice captures that idea by describing something that goes well with something else. When two items complement each other, they pair harmoniously or complete the overall effect, like a wine that complements a dish or a scarf that complements an outfit. The sense of completing or making something perfect is related, but the everyday use most people rely on is the pairing or matching idea—which is exactly what “go well with” expresses. The other ideas—hindering or replacing—do not describe this harmonious pairing.
