Which meaning best describes 'apt' in everyday usage?

• A. Likely to do something; having a tendency to do something
• B. Exactly suitable; appropriate
• C. Not suitable
• D. Quick to learn or understand

Answer: (B)

Apt in everyday use most often signals suitability or fittingness. When something is described as apt, it is seen as just right for the situation—well-chosen, appropriate, or fitting. For example, an apt remark hits the moment exactly, or an apt analogy makes a point clearly. That broad sense of being well-suited to the context is why this option is the best choice.

There are other valid senses of apt in more specific phrases—apt to do something means likely to do something, and an apt student or person is quick to learn. Those uses exist, but they’re narrower in everyday, general meaning than the sense of being appropriate or fitting. The opposite sense, not suitable, would be incorrect.
