Ross's Family Lives in Ontario

Ross's family lives in Ontario.His parents gave him a credit card in his own name for his 14 birthday.For the past 20 months they have always paid the bills for charges made on the card.Last night,Ross's father told him that they were tired of his extravagance and that from now on,he will have to pay any charges himself,including the one that triggered Ross's father's comment to his son.This bill is for $1,200 for a Florida spring break holiday from which Ross has just returned.

A) Since the credit card is in Ross's name,he is responsible for making the payments,including the one for $1,200.
B) Since a holiday is a necessary,the credit card company can hold Ross's parents to paying the bill since they are obliged to support a child under age 16.
C) Ross's parents are liable for any charges on the credit card until they inform the credit card company that they will no longer pay such bills.
D) Since Ross may,as his parents' "agent of necessity," pledge their credit to provide for himself,the parents are liable for his bills until he is 18 years old.
E) A minor cannot be sued for non-necessaries,so Ross's parents must continue to pay for his purchases until either he turns 18 or the credit card company takes back the card,whichever comes first.
