The correct answer is D) engage in more rough-and-tumble play and are more aggressive than girls.
Preschool boys: engage in more rough-and-tumble play and are more aggressive than girls.
Yes, it is true that preschool boys are more prone to play games with physical contact, more aggressive, we can say, than girls. At that age, boys do not distinguish that girls are more delicate than boys. SO boys treat girls the same way. That is why is common to find these kinds of conflicts in kinder garden and preschool.
It is important that teachers pay special attention when organizing activities or playing time with boys and girls together, so no one can get hurt.
