Companies that want to maintain their share in the market frequently adopt a ________ strategy

Robin and Batman, both merchants, orally agree in a contract for the sale of $5000 of black crepe capes.

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.
