Marla offers to sell Kennedy her property on Lake of the Ozarks for $90,000. Marla drafts a written agreement that contains the property description and price, and has places for both Kennedy and Marla to sign. Marla sends the agreement to Kennedy to review. Kennedy signs the agreement and sends it back to Marla, who never signs it. Marla then has second thoughts about the deal and refuses to complete the transaction. If Kennedy tries to enforce the contract against Marla, Kennedy:

a. will be unsuccessful, because Kennedy signed the agreement.

b. will be unsuccessful, because Marla never signed the agreement.

c. will be successful, because Kennedy signed the agreement.

d. will be successful, even though Marla never signed the agreement.
