Which of the following best describes a click-on-agreement?

A click-on-agreement is characterized by a user expressing consent to terms and conditions by clicking a button, typically labeled with phrases like "I agree" or "Accept." This method is widely used in online transactions and digital services, signifying that the user has read and accepted the terms before proceeding. It relies on the principle of mutual assent, where the clicking action represents the user's agreement to be bound by the terms stipulated.

This option stands out because it accurately captures the modern practice of reaching agreements in the digital environment, where parties may not be physically present but can still create binding contracts through their actions online. In contrast, the other options represent traditional methods of forming agreements that do not align with the digital context of a click-on-agreement. Therefore, option C is the best description of a click-on-agreement.
