Model Answer
(C) It maintains posture and precision of voluntary actions.
Explanation
The textbook states the cerebellum "is responsible for precision of voluntary actions and maintaining the posture and balance of the body." Option C matches this exactly. The medulla (hind-brain) controls involuntary actions; the fore-brain handles thinking; the mid-brain relays sensory signals.
