Answer:
A) associative play
Step-by-step explanation:
In 1929, Mildred Parten Newhall developed the theory of Play Stages.
Parten examined groups of pre-school children between the ages of 2 and 5 and developed a series of 6 playing stages; Unoccupied, Solitary, Onlooker, Parallel, Associative and Cooperative.
Associative play is a type of play that involves a group of children participating in similar or identical activities without structured organization, group purpose, group interaction, or a distinct objective.
