Correct answer: C — Advise condoms and arrange ultrasound to locate the device

Missing threads require pregnancy exclusion, advice to use additional precautions, and imaging to confirm intrauterine location. Blind removal risks trauma and may fail if the device is intrauterine with retracted threads. Reassurance without locating the device could miss expulsion or perforation.
