Correct answer: C — LMWH (enoxaparin) for 5 days then warfarin

DVT in pregnancy requires LMWH (enoxaparin weight-based dosing). DOACs are contraindicated in pregnancy (cross the placenta). Warfarin is also contraindicated in the first and third trimesters (teratogenic, fetal haemorrhage risk). LMWH is continued throughout pregnancy and for at least 6 weeks postpartum (minimum total 3 months treatment).
