What word means 'chief' or 'most important'?

• A. Anterior
• B. Priority
• C. Prime
• D. Procure

Answer: (C)

Think about a word that signals the top or central status of something. A term that commonly describes the chief or most important aspect is prime. As an adjective, prime means foremost in rank, importance, or quality—used in phrases like prime concern, prime objective, prime example. It conveys that something is at the top level, not just important among a list but the main one. The other words don’t fit as well: anterior means in front or earlier in time, not about importance; procure is a verb meaning to obtain; priority relates to what should be done first or given precedence, rather than labeling something as the top or chief itself. Therefore, prime best captures “chief” or “most important.”
