Solution

The correct option is D
The calcium causes the release of acetylcholine

An action potential at the pre-synaptic terminal and causes voltage gated calcium channels in the presynaptic membrane to open. Calcium ions enter the presynaptic terminal and initiate the release of the neurotransmitter acetylcholine from the synaptic vesicle.

Q. Assertion :A neuron chemically communicates with a myocyte by releasing acetylcholine into the myoneural junction. Reason: Acetylcholine diffuses across the nerve-muscle synaptic-cleft and binds to receptors on the sarcolemma which gets depolarized.
