Correct answer: C — Ulipristal acetate 30 mg within its 120-hour treatment window

The best answer is “Ulipristal acetate 30 mg within its 120-hour treatment window”. Ulipristal is licensed to 120 hours and is generally more effective than levonorgestrel later in that interval. The asthma caution concerns severe asthma controlled with oral glucocorticoids, which is specifically absent. Double-dose levonorgestrel is considered for higher weight or enzyme induction, not simply for presentation after 72 hours. A copper IUD remains the most effective emergency method, but she has declined it.
