Correct Answer is A
Explanation
The correct answer is a. "Children play alongside each other but do not interact."
Choice A reason: Parallel play is characterized by children playing next to each other without engaging in direct interaction or cooperative play, which is typical behavior at certain developmental stages.
Choice B reason: Organized play involves interaction and cooperation, which is not characteristic of parallel play.
Choice C reason: While children may play independently in a group, this statement does not capture the essence of parallel play, which involves proximity without interaction.
Choice D reason: Observing others play is more indicative of onlooker behavior rather than parallel play.
