Answer:
C) tender.
Step-by-step explanation:
In contract law, a tender offer to perform is conditioned to the moment when the other party is willing and ready to perform as well. In this case, CrossCountry signed a contract, but the contract will be valid when the other party (Discount Outlet Stores) needs their services. If the other party does not require their services, CrossCountry is not able to perform nor demand performance.
