Something that is prevalent happens frequently or often.

To determine which option best describes the meaning of prevalent, we can break down the word and analyze its components.

The word "prevalent" is an adjective derived from the verb "prevail." To prevail means to be dominant, widespread, or to have a significant influence.

Based on this definition, we can eliminate option a, "very rarely," since something prevalent is the opposite of being rare.

Option b, "occasionally," also does not fit the definition of prevalent. Occasionally means happening from time to time or infrequently, which is not consistent with the idea of being dominant or widespread.

This leaves us with option c, "often." Something that is prevalent happens often or with a significant frequency.

Therefore, the best option to complete the sentence is c, "often."
