Which of the following is NOT a way a contract may be discharged?

Contracts can be discharged in various ways, and understanding these methods is crucial in contract law. One of the primary means of discharging a contract is through performance, where both parties fulfill their obligations as specified in the contract. Breach, another method, occurs when one party fails to meet their contractual obligations, allowing the other party to terminate the contract or seek damages. Frustration refers to situations where an unforeseen event makes the performance of the contract impossible due to circumstances beyond the control of the parties.

Weather conditions, while they can affect the ability to perform a contract, do not independently discharge a contract. For example, if a contract requires an outdoor event, poor weather does not automatically release the parties from their duties unless it meets specific legal standards for frustration or impossibility. Therefore, weather conditions themselves do not constitute an established ground for discharging a contract, making this the correct choice as it is not a recognized method for contract discharge within the framework of contract law.
