Answer: The correct answer is-
C. a species evolves at a slow, steady pace.
Gradualism can be describesd as a pattern/ theory of evolution by which already existing species give rise to new species by means of slow/ gradual and steady changes instead of major and abrupt changes.
Over long period of time, the small changes (that are beneficial for their survival) result in new species.
Example- Tiger that is evolved pattern of stripes ( which give them better advantage to hide in tall grass).
Thus, option C) a species evolves at a slow, steady pace. is the right answer.
