Correct answer: A — Jatene (arterial switch) operation

TGA with intact septum requires the arterial switch operation (Jatene procedure), typically performed within the first 1-2 weeks of life. The coronary arteries are translocated to the neo-aorta. Balloon atrial septostomy (Rashkind) may be needed as a temporising measure to improve mixing at the atrial level.
