Answer:
d. Willis breached the contract, but the breach was not material.
Step-by-step explanation:
Willis agree to built a new home for Robert. The contract price was $300,000. Robert specified the features for the new home and since he is very picky he did not wanted to compromise on the specification he decided. Willis made a mistake and faucets and linoleum flooring are not exactly what Robert specified. The amount required to put the faucet back to its condition which Robert specified is $300 which is 1 percent of the total contract amount. The amount of breach is not material but Willis has breached the contact with Robert.
