B Correct answer
Explanation

At the left lung hilum, structures are arranged from superior to inferior: pulmonary artery (most superior), bronchus, and pulmonary vein (inferior). This anatomical relationship is consistent on the left side, though slightly different on the right where the eparterial bronchus is superior to the pulmonary artery.
