Nina contracts with Office Suites Corporation to buy a suite in its Prospect Point Tower at a premium because of its undisturbed view of Quay Harbor. Unforeseeably, the town of Quay Harbor changes the zoning law, and Resort Hotels, Inc., constructs Seaview Resort, blocking what would have been Ninas view. Ninas best argument for a change in the Office Suites contract or its price is:a. Frustration of purpose.b. Objective impossibility of performance.c. Anticipatory repudiation.d. Commercial impracticability.
