Correct answer: D — Test for GAS by RADT or culture before treating infection
Explanation lettering: E = shown as A · D = shown as B · A = shown as C · C = shown as D · B = shown as E
C is correct. This has high pre-test probability for GAS/scarlet fever; microbiologic confirmation guides antibiotics. D, E, A and B do not fit as well.
