Which word means 'a coworker'?

• A. Commission
• B. Commitment
• C. Colleague
• D. Commodity

Answer: (C)

The main concept here is identifying a term that names a person you work with in a professional setting. The best fit is colleague, because it specifically means a person who is part of the same workplace or profession and shares similar work context with you. That makes it the precise way to say someone you collaborate with at work.

Commission refers to a fee or a group assigned to perform a task, so it’s not a person. Commitment means dedication or a pledge, not a person. Commodity is an economic good or raw material, not a person. For example, you’d say, “I discussed the project with my colleague,” which clearly uses the word that denotes a coworker.
