Correct answer: D — Offer double-dose levonorgestrel emergency contraception

Enzyme-inducing drugs reduce the effectiveness of oral emergency contraception; if a copper IUD is declined, FSRH recommends double-dose levonorgestrel. Ulipristal is affected by enzyme induction and is not preferred in this context. Carbamazepine does not improve oral EC efficacy. Some EC is still better than no EC after counselling when IUD is declined.
