i dont know yet

Explanation:

In the parasympathetic division of the autonomic nervous system, the neurotransmitter released at the synapse (specifically the neuromuscular or neuroglandular junction) is acetylcholine. Norepinephrine is mainly associated with the sympathetic division. Epinephrine is a hormone (also a neurotransmitter in some cases but not the primary one for the parasympathetic division's synapse in question here).

Answer:

Acetylcholine only
