Pat is pledging at the Delta Upsilon Delta $($DUD$)$ fraternity in order to become a member. As part of his initiation, he must eat a piece of cheese that is on a mousetrap that has been set to trap a mouse. He tries, but the trap slams shut on his nose, injuring him. Pat files a products liability suit against the hardware store which sold the mousetrap to the fraternity members. Which of the following, if true, would allow the hardware store to avoid liability?

The store exercised reasonable care in selling the mousetrap.

It was an unforeseeable misuse for anyone to use a mousetrap in this way.

Any defect in the mousetrap was caused by the manufacturer, not the hardware store.

Pat was not the purchaser from the hardware store.
