الإجابة: B. Oral Amoxicillin
Streptococcus pyogenes pharyngitis is treated with oral penicillin (penicillin VK) or amoxicillin, so oral amoxicillin is the answer. Fosfomycin is a urinary agent, metronidazole covers anaerobes/protozoa, and ciprofloxacin has poor streptococcal cover and is not used for strep throat.
