Correct answer: C — Aortic stenosis

An ejection systolic murmur at the right upper sternal border (aortic area) radiating to the carotids, with an associated thrill and LVH, is characteristic of aortic stenosis. Exertional syncope in the context of aortic stenosis is an ominous finding suggesting severe obstruction. Echocardiography and cardiology review are urgent.
