Correct answer: C — Functional hypothalamic amenorrhoea

Low energy availability, low BMI, high exercise load and amenorrhoea suggest functional hypothalamic amenorrhoea. PCOS is more associated with hyperandrogenism and often higher BMI, although it can occur in lean women. PID causes pelvic pain and infection signs. Management includes nutritional rehabilitation and bone-health assessment.
