Clark was interested in buying Smithson's bakery but was hesitant because he knew a master baker had recently moved to town. Smithson therefore got the baker to promise not to open a bakery for three years in exchange for $5,000. Clark brought the bakery after Smithson's completion of the contract with the baker. Smithson's contract with the baker is:
a. enforceable.
b. enforceable if Smithson can show it was reasonably limited in time and area.
c. enforceable if Smithson can show it was reasonably necessary to the sale of his business.
d. enforceable if Smithson can show the baker would probably not have opened a bakery anyway.
e. none of the above.
