Jen, Jeff, and Mary usually have dinner together every Friday night during term. Each would take a turn paying for the meal. This Friday is Jeff's turn but he has to study for the mid$-$term next Monday so he phoned to say he is busy and can't make it$.$ Which one of the following is the best statement about the legal position of the parties?

This is not a social relationship and the agreement will always be binding on the parties.

There is not enough information to make a decision.

Jen and Mary should go for dinner anyway and send the bill to Jeff who has a legal obligation to pay.

If it can be shown that all three had an intention to make a binding contract, the court will enforce the terms.

Jeff should send an amount of money to cover at least his share of the bill to Jen and Mary.
