Solution
The correct option is C Acetylcholine Acetylcholine behaves as an excitatory neurotransmitter at the neuromuscular junction in skeletal muscle. It is an organic molecule that acts as a neurotransmitter in many organisms including humans. It is one of the neurotransmitters in Autonomic Nervous System (ANS). It acts on both Peripheral and Central Nervous System, i.e. PNS and CNS. It also has an inhibitory effect which lowers the heart rate in cardiac tissue.
