The correct answer for this question is Acetylcholine receptors at the neuromuscular junction i.e., B
The most basic type of is one in which a single protein or complex of proteins performs both hormone binding and signal generation. Ligand-gated ion channels are included in this category. They consist of two major components: a ligand-binding domain accessible from the cell's surface and a transmembrane domain containing a channel. Binding of ligand to the receptor's exofacial surface causes a conformational change that results in the opening of a pore, allowing specific ions to travel across the plasma membrane through the channel.
