A Correct answer
Explanation

Role of sodium and potassium ions in the body is to maintain the body osmotic pressure. Whenever there is an increase in sodium and potassium concentration in the blood, the kidney releases most of it in order such that there will be enough water for use by the body. But when there is a decrease in their concentration, there is more release of water to store more sodium which the body needs dearly. This process is known as osmoregulation.
