Stella Bought a Cup of Coffee at the Drive-Through Window

Stella bought a cup of coffee at the drive-through window at a coffee-shop. Holding the cup between her knees and attempting to take off the lid to add cream, she spilled the coffee. She suffered burns to her thighs. If this happened in Canada, which of the following is true?

A) To succeed with the defense that she volunteered to take the risk, the coffee-shop would have to prove that she deliberately spilled the coffee.
B) If the coffee-shop claims there was no way to reasonably foresee that Stella would be harmed, the plaintiff's case would be dismissed even though she suffered burns.
C) If Stella sues the coffee-shop for negligence, she will only have to prove that the company owed her a duty of care.
D) If Stella sues the coffee-shop, the company's best argument is that it didn't owe her a duty of care.
E) If the court finds the plaintiff contributorily negligent causing 60% of her loss, she must suffer that portion of the loss and will not be compensated for it by the defendant.
