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

• A. Prime
• B. Principal
• C. Priority
• D. Process

Answer: (A)

Understanding synonyms for "most important" is what this item tests. The best match is prime, because prime is used to signal the highest level or most important status, as in prime concern or prime objective. It conveys a sense of top priority and central importance. While principal can mean main or leading, it is often tied to roles or entities (like the principal of a school) rather than a universal sense of utmost importance. Priority refers to something that should be attended to first, which is about order or urgency rather than inherent importance. Process, on the other hand, is a series of actions and is unrelated to importance.
