Correct answer: B — Intravenous immunoglobulin with aspirin and echocardiography

This is Kawasaki disease, and treatment with IVIG plus aspirin reduces coronary artery aneurysm risk; echocardiography is required. Waiting for infectious tests risks missing the treatment window when the clinical criteria are met. The pearl is that persistent fever with mucocutaneous signs should prompt Kawasaki assessment even when no single test confirms it.
