According to the Doctrine of Frustration of Purpose

According to the doctrine of frustration of purpose:

A) complete performance is not achieved because of minor deviations from the agreed-upon performance.
B) the promisor is stopped from denying the existence of a contract where the promisee has detrimentally relied on that promise.
C) where both parties know the purpose of a contract and, through no fault of either party, the reason for the contract no longer exists, the contract is terminated.
D) in a contract for the sale of goods, one or more terms may be missing but the court can find a contract, nonetheless, where the parties have intended to make a contract.
