What must acceptance follow in terms of communication methods?

Acceptance must be communicated through methods that have been specifically prescribed or stipulated in the contract or agreement. This ensures that both parties have a clear understanding of how acceptance should be conveyed, which helps avoid any ambiguity or misinterpretation.

When an offer is made, the method of acceptance can be crucial for the formation of a binding contract. If a certain method is required, accepting the offer through a different method may not constitute valid acceptance. By adhering to the prescribed communication methods, the parties can ensure that acceptance is executed properly, thus safeguarding the contractual process.

The other options may imply flexibility or informality, which can lead to complications in establishing the validity of acceptance. For example, any communication method chosen could lead to misunderstandings if one party expected to receive acceptance through a formal channel while the other used an informal means. Similarly, informal notifications or digital communication standards may not align with the needed formal processes required for proper contract acceptance if they do not comply with the stipulated methods in the agreement.
