Correct answer: D — Formal developmental assessment with audiology evaluation

Language delay with reduced social communication and repetitive behaviours suggests autism spectrum disorder, requiring formal developmental assessment; hearing should be assessed because hearing impairment can mimic or compound language delay. Waiting until school entry delays support. Bilingual exposure does not cause autism or clinically significant language disorder.
