Tom verbally promised to give $10,000 to his son Hank as a birthday gift on the day that Hank turns 18 years of age. If Hank's father refuses to pay the $10,000 to Hank when Hank turns 18 and Hank sues his father for breach of contract, Hank will most likely:

a. Loss because no enforceable contract ever existed between Tom and Hank.
b. Loss because Hank did not give up anything in exchange for Tom's promise to pay Hank $10,000.
c. Loss because Tom and Hank's contraçt was required by the Statute of Limitations to be in writing to be enforceable in court
d. Win because a voidable contract existed between Tom and Hank that could only be enforced by Hank but not by Tom
