Correct answer: C — Magnesium sulfate

Eclampsia is seizure activity in the setting of preeclampsia and magnesium sulfate is first-line for seizure control and prevention. Benzodiazepines may be needed for refractory seizures, but they do not replace magnesium. Valproate and warfarin are teratogenic concerns and are not the acute obstetric treatment.
