Which of the following is a method to terminate a contract?

Performance is a recognized method for terminating a contract because it occurs when all parties fulfill their obligations as stipulated in the agreement. This means that the contract is completed as intended, resulting in the termination of any further responsibilities or liabilities related to the contract. Upon performance, both parties are released from their contractual duties because the goal of the contract has been achieved.

In contrast, options like goodwill, negotiation, and intention do not directly lead to the termination of a contract in a clear or formal manner. Goodwill often pertains to the amicable relationships and reputations built between parties, which may facilitate future interactions but does not serve as a method to formally terminate a contract. Negotiation can lead to modifications or mutual agreements, but it does not inherently imply the end of a contractual relationship without a clear performance or completion. Intention refers to the mindset or purpose behind entering into a contract and does not serve as a standalone means to terminate an existing agreement.
