Margaret owned a Basset Hound puppy that showed great prospects of developing into a championship show dog. Bob purchased the puppy for $500 and, in payment, agreed to paint Margaret's house. Shortly after the puppy was delivered to Bob, it developed a disease which killed it. Bob refused to perform the work as agreed, and Margaret sued. The court likely would hold that: (A) the agreement was voidable for fraud (B) no contract resulted because of lack of consideration (C) no contract resulted because of mutual mistake (D) a valid contract was formed.
