Correct answer: C — Fontan completion (total cavopulmonary connection)

Single ventricle palliation follows a staged approach: Stage 1 (Norwood or BTS shunt, neonatal), Stage 2 (bidirectional Glenn/hemi-Fontan, 4-6 months), Stage 3 (Fontan completion, 2-4 years). The Fontan connects the IVC to the pulmonary arteries, completing the total cavopulmonary connection.
