Explanation:

Systemic infant motor development refers to a predictable, ordered progression where simpler skills are mastered first, building up to more complex ones. The other options are incorrect: mirroring peers is not the defining systemic mechanism, caregiver coaching is not required for this innate sequence, and myelination occurs gradually alongside development rather than needing full completion first.

Answer:

D. in a sequence of increasing complexity
