What is a "breach of contract"?

A breach of contract occurs when one party fails to fulfill their obligations as stipulated in the agreement. This can manifest in various forms, such as not delivering goods, not paying on time, or failing to perform a service as agreed. In contract law, a breach can be categorized as either material or minor, depending on the significance of the failure and its impact on the contract's execution.

The choice relating to offering modified terms is not considered a breach itself, as it may stem from an attempt to negotiate or resolve issues within the contract rather than a failure to comply with it. Similarly, supporting another party's claims and negotiating a new contract do not constitute a breach; these actions are part of the contract management process and can occur within a contractual relationship without indicating any failure to perform obligations. Therefore, the essence of identifying a breach lies in the failure to meet the commitments made in the contract, which is precisely what the correct choice describes.
