Harry called his mother, Harriet, to tell her that they had just had a baby girl and named her Harriette. Harry's mother cried and said, "I'm so happy that you have named the baby after me that I'm going to send you $100 for her!" Harriet did not send the money. Is Harriet's promise enforceable as a contract?

a.) No, because there is no consideration

b.) No, because the baby was probably named after her father

c.) Yes, because Harry gave up the legal right to give the baby a different name in exchange for the money

d.) Yes, because Harry anticipated that she would send some money to the baby
