الإجابة: A. Right coronary artery
ST elevation in II, III and aVF = inferior STEMI, which is usually due to right coronary artery occlusion. The LAD causes anterior changes (V1–V4), and left main occlusion gives widespread changes.

A
ليش صح
The RCA supplies the inferior wall, and its infarction shows in leads II, III, aVF (and right-sided leads).

ليش غلط
The LAD supplies the anterior wall (including the septum), with ST changes in V1-V4, not II, III and aVF.

C
ليش غلط
II, III and aVF are the inferior (RCA) leads. The left-sided vessels are linked to other leads: the LAD to V1-V4 and the circumflex (lateral wall) to I, aVL, V5 and V6.
