Carla Contractor Company contracts to build a house for Lisa for $500,000. The house is completed on time and is in conformity with contract specifications except that Carla's workers forgot to put in Kohler plumbing fixtures in the master bathroom and instead mistakenly put in another slightly less expensive and not as prestigious brand. Otherwise the house is fine and is in conformity with the contract, but now Lisa refuses to pay for the construction of the house, saying the performance was defective due to the mistaken fixtures. What is the likely legal result of this dispute?
a. Lisa is discharged from any and all contract responsibility and does not have to pay anything and can successfully sue Carla for breach of contract.
b. Lisa can sue and prevail since under the Uniform Commercial Code Carla's performance was not perfect.
c. Lisa must pay Carla the agreed upon contract price minus an amount to correct the defect since the "substantial performance" doctrine of the common law prevails.
d. Lisa can sue for "pain and suffering" damages since she was stressed out by the "inferior" plumbing fixtures.
