What are Smooth muscles?
Because it lacks sarcomeres and as a result, striations, smooth muscle is an involuntary non-striated muscle (bands or stripes). Its two subgroups are single-unit smooth muscle and multi-unit smooth muscle. A syncytium is the collective contraction of the sheet or bundle of smooth muscle cells that make up a single-unit muscle.
Smooth muscle makes up the walls of hollow organs including the stomach, intestines, bladder, and uterus as well as the blood and lymphatic vessels, as well as the tracts of the respiratory, urinary, and reproductive systems. The ciliary muscle, a type of smooth muscle present in the eyes, changes the shape of the lens by dilation and contraction of the iris.

Answer:
The correct answer is - reuptake of the neurotransmitter molecule into the axon through a membrane transporter.
Explanation:
The action of a neurotransmitter at the postsynaptic cell or postsynaptic potentials is terminated by any of these mechanisms that are enzymatic degradation, diffusion or reuptake into the presynaptic cell by specific transporters.
After the desired biological response by postsynaptic potentials, in order to avoid over stimulation or termination of the postsynaptic potentials the neurotransmitter is taken back into the axon through a membrane transporter. This mechanism is to maintain a balance.
