Which type of play is most developmentally appropriate for a group of toddlers in a playgroup setting?

A. Parallel play, where children play alongside each other without directly interacting, is typical for toddlers. It allows them to develop social awareness while still focusing on their individual activities. B. Cooperative play, which involves playing together with shared goals, typically emerges in older children, around age 4-5. C. Solitary play is more characteristic of infants and very young toddlers, but by the toddler stage, children engage in parallel play. D. Dramatic play (pretend play) does occur in toddlers but is more individual. Parallel play is more common in group settings.
