This approach ensures that the child receives the necessary treatment while also acknowledging their desire to continue playing in the playroom.

Rationale: The correct answer is C, parallel play. Parallel play is observed when children play alongside each other but do not directly interact. In this scenario, each child is engaged in their own activity without engaging or influencing each other's play, which characterizes parallel play. Cooperative play (choice A) involves children playing together towards a common goal, which is not evident in the given situation. Solitary play (choice B) is when a child plays alone, unrelated to the presence of others. Associative play (choice D) involves more interaction and sharing of toys between children, which is not happening in the described play scenario.
