this preganglionic fiber releases norepinephrine
○ nicotinic
○ muscarinic
○ adrenergic
○ cholinergic

Explanation:

To solve this, we analyze each option:

• Nicotinic and muscarinic are receptors, not related to norepinephrine release.
• Cholinergic fibers release acetylcholine, not norepinephrine.
• Adrenergic fibers (or preganglionic fibers in some cases, though typically postganglionic sympathetic, but the key is norepinephrine release) are associated with norepinephrine. So the correct option is adrenergic.

Answer:

C. adrenergic
