Solution

The correct option is C

Repolarization


The onset of the action potential in a polarized neuron triggers repolarisation.

The onset of an action potential is marked by the opening of voltage-gated Na+ channels. The depolarization that occurs due to this, causes the neuron membrane to attain a voltage that triggers the opening of voltage-gated K+ channels. Then K+ ions rush out through this channels, reducing the positive charge inside the neuron, it causes repolarization of the neuronal membrane.
