Correct answer: E — 5 days

Uncomplicated lower UTI in children >3 months can be treated with a short course of oral antibiotics (3-5 days per Australian Therapeutic Guidelines). Febrile UTI/upper UTI (pyelonephritis) requires 7-10 days. Short courses for lower UTI reduce antibiotic exposure and resistance without compromising outcomes.
