Answer:
C) if the court finds that Shawn has substantially performed, he will be able to recover the contract price less any damages caused by his failure to perform as promised.
Step-by-step explanation:
From the question Harry signed a contract with Shawn to build a house. Harry made some specification to build the house. But Shawn did not follow the specifications now Harry doesn't want to pay him the contract amount.
Under doctrine of specific performance, Harry can pay less money than the contract price. Because Shawn has performed substantially, he is not entitled to receive the contract price as agreed.
