Final answer:
The most commonly performed surgery to correct D-transposition of the great vessels is the arterial switch procedure, which restores the correct arrangement of the pulmonary artery and the aorta (Option 2).
Step-by-step explanation:
The surgical procedure currently most commonly performed to correct D-transposition of the great vessels is the arterial switch procedure.
This surgery corrects the condition by detaching the pulmonary artery and the aorta from their incorrect positions and reattaching them to their correct locations.
It is preferred over the atrial switch procedure as it creates a physiologically normal circulation. The Fontan procedure is generally used for different types of heart defects where there is only one functional ventricle.
A Ventricular septal defect closure is performed to seal a hole between the heart's ventricles and is not the primary surgery for correcting D-transposition of the great vessels.
Therefore, the correct answer to the student's question is (Option 2) Arterial switch procedure.
