How Do Muscarinic Receptors Differ from Nicotinic Receptors

How do muscarinic receptors differ from nicotinic receptors?

A) Muscarinic receptors are located on the cell membranes of the visceral organs and glands, whereas nicotinic receptors are located on the cell membranes of skeletal muscles and at the ganglia of nerves.
B) Muscarinic receptors are cholinergic receptors, whereas nicotinic receptors are adrenergic receptors.
C) Muscarinic receptors are stimulated by acetylcholine released from preganglionic nerve endings, whereas nicotinic receptors are stimulated by acetylcholine released from postganglionic nerve endings.
D) Muscarinic receptors are somatic, whereas nicotinic receptors are autonomic.
