While in the pediatrician's office for their child's 12-month well child exam, the parents ask the nurse for advice on age-appropriate toys for their child. Based on the child's developmental level, which type of toy should the nurse suggest?

A. While soft toys are appropriate for younger infants, a 12-month-old will be more interested in toys that engage movement and exploration. B. Puzzles with many pieces are more appropriate for older toddlers, around 2 years of age. C. At 12 months, toddlers enjoy push-and-pull toys, which help develop motor skills and coordination. D. Toys with black-and-white patterns are more appropriate for newborns and younger infants, not a 12-month-old.
