D Correct answer
Explanation

The conduction of an electric impulse from one nerve cell to a muscle cell either to inhibit or induce the muscle contraction happens via paracrine signaling, where in the signaling molecules secreted by a cell affect the target cells that are in close proximity to the cell that secretes them.
