__ ions leave the cytoplasm rapidly during the repolarization phase. both A and C none of the above Calcium Sodium Potassium

Potassium ions

Explanation:

During repolarization, more potassium ions leaves the cell making the cell less positive and more negative bringing about repolarization.

The event of repolarization comes after the depolarization of the cell wherein more sodium ions which are positively charged flows into the cell letting the cell become less negative leading to depolarization of the cell.
