Correct answer: A — Azithromycin (consider resistance)

For GAS pharyngitis with true penicillin allergy, macrolide can be used (consider local resistance). Cephalosporins risk cross-reactivity in anaphylaxis. Amoxicillin inappropriate with allergy. Levofloxacin not first-line. No antibiotics incorrect with positive test.
