Correct answer: B — B. Aspirin plus a P2Y12 inhibitor and urgent reperfusion therapy

An ST-elevation myocardial infarction (STEMI) in the inferior leads indicates urgent reperfusion (primary PCI if available, or thrombolysis if PCI is unavailable within recommended time). Aspirin plus a P2Y12 inhibitor is standard. Oxygen is given only if saturations are below around 94%, not universal. Morphine provides pain relief but does not address reperfusion.
