A Preschooler Knows She Should Not Ram Her Tricycle into the Garage

A preschooler knows she should not ram her tricycle into the garage door at home, but she does this at a friend's house. What is the most logical reason for this difference in behavior at home and at the friend's house?

A) The preschooler values her own house more than she values the house of a playmate.
B) The child's mother is much stricter and supervises children much more closely than the playmate's mother.
C) A young preschool child may have difficulty applying known rules to a different situation.
D) There is a higher level of frustration when outside her own home and play territory.
