Correct answer: C — Adenotonsillectomy

Adenotonsillectomy is the first-line treatment for moderate-severe OSA in children with adenotonsillar hypertrophy. It resolves OSA in ~75% of non-obese children. Post-operative polysomnography should be considered in children with severe OSA, obesity, or craniofacial abnormalities to confirm resolution.
