Which term describes the least likely probability category?

• A. Frequent
• B. Likely
• C. Occasional
• D. Unlikely

Answer: (D)

In risk words, we use qualitative labels to signal how often something might happen. Frequent means it happens a lot, Likely means it has a high chance, and Occasional means it happens but not regularly. Unlikely is the one that signals a very low chance, describing something not expected to occur often. So, the term that describes the least likely probability category is Unlikely. It contrasts with the others by indicating a small probability, not a common or expected occurrence.
