Johnny, age 16, buys a car from Fred for $6,000 and agrees to pay him $500 per month for 12 months. Before turning 18, Johnny makes the last payment. A court would probably hold that:
a) The contract is valid and enforceable.
b) The contract is voidable due to Johnny's age.
c) Fred breached the contract by selling to a minor.
d) The contract is void because it involves a minor.
