Alice entered into a written agreement with Moran, whereby Moran agreed to remodel the basement of Alice's home, and Alice agreed to pay Moran $8,000 upon completion of the job. The agreement contained a list of specifications as to the types of materials to be used in the remodeling. Among these specifications was a provision that Moran was to use an imported Brazilian hardwood for the paneling. Moran began the job, and then assigned his right to payment under the agreement to Nicholls. When the job was a little more than half completed, Alice sold the house to Bill. In a document separate from the deed of conveyance, Alice assigned her right to Moran's labor and delegated her duty to pay under the contract to Bill. Moran completed the job on time, but he used Wyoming knotty pine instead of Brazilian hardwood for the paneling. The effect is quite different and the knotty pine is much less expensive than the imported hardwood. Who can Bill sue for breach? Select one: a. Alice only. b. Nichols only. c. Bill only. d. Alice and Moran only e. None of the above.
