Correct answer: A — Surgical division of the vascular ring

Vascular rings (double aortic arch, right aortic arch with aberrant left subclavian) cause tracheal and oesophageal compression. Symptomatic vascular rings require surgical division. Most children have complete resolution of symptoms after surgery, though tracheomalacia at the compression site may persist temporarily.
