Correct answer: B — Treat chlamydia and leave IUD in situ

If chlamydia is identified after insertion and the patient is well, treat infection and usually leave the IUD in place. Removal is not needed unless pelvic infection fails to improve or the user requests removal. This is a common near-miss.
