Robin and Batman, both merchants, orally agree in a contract for the sale of $5000 of black crepe capes. Batman, the buyer, sends to Robin, the seller, a written confirmation of the sale, which is sufficient against Batman under the Statute of Frauds and which Batman signs. Robin fails to perform the contract and refuses to ship the goods and says he never signed it and is not bound. Holy Crepe Capes! Batman sues. This contract is:

a. unenforceable, because Robin did not sign any contract.
b. unenforceable, because Batman did not pay for the goods.
c. enforceable, because Batman sent the written confirmation of the sale, thereby partially performing the contract.
d. enforceable even without Robin's signature because both parties are merchants.

Ans: d. enforceable even without Robin's signature because both parties are merchants.
