Harold offers to sell Emma his farmland in Bryson County. After discussing the sale at length in front of their friends Nicole and Jackson, Harold and Emma orally agree on a price of $120,000 for the land. The next day, Emma goes to the bank and withdraws $120,000 to pay Harold for the land. When Emma presents the $120,000 to Harold, Harold tells Emma he was just joking and does not wish to sell the land. Emma tries to enforce the deal, and Harold continues to refuse by saying that the deal was not in writing, and, therefore, it is unenforceable. The contract between Harold and Emma for the sale of the land: a. is not enforceable because of the theory of promissory estoppel.

b. is not enforceable because it violates the statute of frauds.

c. is enforceable, because there are witnesses to the deal.

d. is enforceable because it complies with the statute of frauds.
