Which statement best distinguishes chorea from tics?

Explanation:
Movements in tic disorders and chorea differ in pattern and predictability. Tics are repetitive and stereotyped, often occurring in clusters and sometimes suppressible for short periods, frequently with a premonitory urge. Chorea, on the other hand, consists of rapid, irregular, and unpredictable movements that seem to flow from one muscle group to another without settling into a repeating pattern. This lack of repetition and the random, wandering nature of chorea is what the statement captures, making it the best description.
