Correct answer: D — Avoid digital vaginal examination and perform ultrasound assessment
Painless third-trimester bleeding with a known low-lying placenta suggests placenta previa; digital examination is avoided until placental location is confirmed because it can provoke severe bleeding. Ultrasound assessment and obstetric review are appropriate. Methotrexate has no role in this situation.
