Correct answer: B — Give IVIG 2 g/kg now and begin daily antiplatelet treatment
Explanation lettering: E = shown as A · A = shown as B · D = shown as C · C = shown as D · B = shown as E
A is correct because ongoing fever and inflammation remain indications for IVIG after day 10; a normal initial echocardiogram neither excludes Kawasaki disease nor removes later coronary risk. B and C undertreat active vasculitis. D and E misapply escalation therapies.
