A session is used to store user information temporarily while the user interacts with a website or web application. If the user remains inactive and does not refresh the page or send any request to the server, the session automatically expires after a fixed amount of time called the session timeout.

In many web technologies such as ASP.NET, the default session timeout value is 20 minutes. Therefore, if no activity is performed for 20 minutes, the page session ends automatically.

Hence, the correct answer is:

C) 20 minutes
