(D) When a stimulus is applied to the membrane of a neuron,the permeability of the membrane to $Na^{+}$ ions increases significantly.This leads to a rapid influx of $Na^{+}$ ions into the intracellular space from the extracellular fluid.This process is known as depolarization,which is the initial phase of an action potential.Therefore,the correct answer is $Na^{+}$.
