Correct answer: C — Oral rehydration solution in small frequent volumes

Mild to moderate dehydration from gastroenteritis is best treated with oral rehydration solution. Sports drinks have inappropriate sugar/electrolyte composition, and antibiotics are not routine for viral diarrhoea. Antimotility agents are generally avoided in young children because of adverse effects.
