Correct answer: D — Oral rehydration solution (ORS)

Mild dehydration in gastroenteritis should be managed with oral rehydration solution (ORS). Per the RCH Melbourne guideline, ORS should be given in small frequent volumes (5 mL every 1-2 minutes). If oral fluids are not tolerated, nasogastric rehydration is the next step before IV fluids.
