1. Niacin
2. Pyridoxine (vitamin B6)
3. Cyanocobalamin (vitamin B12)

Rationale 2: Pyridoxine prevents peripheral neuropathy.
Rationale 3: Cyanocobalamin does not prevent peripheral neuropathy.
Rationale 4: Neurontin does not prevent neuropathy.
Global Rationale: Pregnant patients should receive isoniazid therapy supplemented with pyridoxine (vitamin B6), which has been shown to prevent peripheral neuropathy. The other drugs do not have this action.
