Answer options

BEven if the child is buckled into a car seat Correct
CEven if a person aged 12 or older stays with the child

The California Driver Handbook says a child 6 or younger may not be left unattended in a vehicle unless someone at least 12 years old is supervising, and a car seat does not change that rule. Heat, cold, and other hazards can endanger a child left alone within minutes.
