C) Marie should make sure she surveys both fathers and mothers.

Step-by-step explanation:

Instead of asking one parent like the father, she should ask both types of parents. Some parents go the mall by themselves not with their spouse. The parents may even have their own separate car so she needs to ask both of them.
