Bryan tells his friend Jane, "I don't think it's fair that you don't have a cell phone and the rest of our friends do. In consideration of that unfairness, I will pay you $400 for you to buy a new automobile. This contract is:
a. enforceable, because it is a bargained-for exchange.
b. enforceable, because it corrects an unfairness.
c. unenforceable, because it is not a bargained-for exchange.
d. unenforceable, because the contract involved a purchase of goods for less than $500.
