Correct answer: B — Transvaginal ultrasound at 32 weeks to reassess placental location

The best answer is “Transvaginal ultrasound at 32 weeks to reassess placental location”. A placental edge less than 20 mm from the internal os at the anomaly scan is low lying. RCOG recommends follow-up imaging at 32 weeks, including transvaginal ultrasound when appropriate, because many low placentas identified at 20 weeks move clear as pregnancy advances. Mode and timing of birth depend on the later placental position, symptoms and individual risk rather than the anomaly-scan finding alone.
