B Correct answer
Explanation

Cholera is caused by cholera toxin released by Vibrio cholerae. The symptoms include severe diarrhoea, vomitting, watery stools. All these result in the dehydration. The cholera toxin activates adenylate cyclase enzyme. This results in the continuous secretion of Cl$^−$, HCO$^{−3}$ and water in the intestine. In saline drip, Na$^+$ ions helps in maintaining the sodium-potassium pump and thus retention of water. Saline drip also provides glucose which will give energy. Hence, patients suffering from cholera are given a saline drip because Na$^+$  ions help in the retention of water in the body tissues.

Thus, the correct answer is 'Na$^+$  ions help in the retention of water in the body tissues.'
