Answer:
C) Lucas.
Step-by-step explanation:
Both UCC and the statute of frauds require that this sale agreement must be written. UCC states that contracts over $500 must be in writing and I suppose the company is worth more than $500. The statute of frauds requires that contracts involving real property, and now again I suppose that Mountain Springs has at least one real property, need to be in writing.
Both regulations establish that a signature must be present in order for the contract to be binding. Since Lucas signed the agreement (it doesn't have to be a contract, only an agreement), then it is enforceable against him. But it is not enforceable against Natural Beverages since they didn't sign it.
