Concept: A legally enforceable agreement between two or more parties is known as a contract.
Explanation: An agreement becomes enforceable only when it satisfies the legal requirements of a valid contract.
These requirements include offer, acceptance, consideration, and the intention to create legal relations.
A warranty is a minor term or promise within a contract, not the agreement itself.
An offer is merely a proposal made by one party, which becomes an agreement only after acceptance.
Consideration is what each party gives or promises to the other, such as money or services.
Therefore, the complete and enforceable agreement between two people is best described as a contract.
Since such an agreement carries the force of law, the parties can seek legal remedies if it is breached.
