Correct answer: E — Top up epidural with 15 mL 0.1% bupivacaine + fentanyl 2 mcg/mL in 5 mL increments

T4 needed for CS. T10 at 10 min is inadequate. Top up epidural cautiously in 5 mL increments of dilute solution. Using 0.5% bupivacaine epidurally risks unpredictable high block. Repeat spinal after epidural dosing is dangerous.
