Solution

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion.
Acetylcholine is the neurotransmitter of vertebrates secreted by both pre- and post-ganglionic parasympathetic cholinergic neurons (autonomic nerve endings). The sympathetic preganglionic neurons release acetylcholine. cholinergic effector organs are the one that is stimulated by acetylcholione and include autonomic organs and skeletal muscles. This makes acetylcholine a predominant neurotransmitter. So, the correct answer is option A.
