Which option correctly orders voluntary, involuntary, and reflex actions?
Answer and explanation
Correct answer: Writing, heartbeat, pulling hand from hot object
The governing concept is classification by control mechanism. Writing is voluntary because it is consciously initiated. Heartbeat is involuntary because it continues automatically under autonomic control. Pulling the hand away from a hot object is a rapid reflex action, usually coordinated through a reflex arc before conscious awareness. Thus option A gives the requested order; the other options mix categories or unrelated processes.
