Correct answer: A — Pelvic inflammatory disease

Pelvic pain with cervical motion tenderness, fever, and mucopurulent discharge is most consistent with PID. Candidiasis causes vulval itch and discharge but not cervical motion tenderness or fever. Ectopic pregnancy is unlikely with a negative pregnancy test. Endometriosis is chronic and cyclic rather than febrile with purulent discharge.
