Laura, Who Has a Dress Shop, Likes a Certain Style

Laura, who has a dress shop, likes a certain style of dress and reaches an agreement with ABC Co., the designer and manufacturer of the dress, that she will purchase all the dresses of that style that ABC Co. can produce for $100 each. Later, ABC Co. learns of Sam, Laura's competitor, who is willing to pay double what Laura agreed to pay for the dresses. ABC Co., attempts to avoid the agreement with Laura on the basis that the agreement with Laura was vague and that consideration was lacking. Which of the following is the most likely result?

A) Laura will win on the basis of promissory estoppels.
B) Laura will win because she had a valid output contract.
C) Laura will win because she had a valid requirement contract.
D) ABC Co. will win because the contract with Laura was insufficiently vague.
E) ABC Co. will win so long as Laura was given sufficient notice of its decision to enable her to obtain dresses from some other manufacturer.
