Answer:
c. the contract is discharged.
Step-by-step explanation:
As the contract is not feasible to be completed not because of any parties of the contract, but because of externalities.
This provides for the no fault conditions on both the parties of the contract.
Here the construction was to be done by the Construction Contractors Inc. for Discount Retail Inc, at a place in Electro City.
But now the construction cannot happen as because Electro City has an amendment providing no construction at the particular place where Discount Retail Inc. wants the construction.
