To answer this question, you need to understand how sessions work in ASP.NET.
In ASP.NET, sessions allow you to store and retrieve user-specific information across multiple requests. Session state is maintained on the server, and a session ID is used to associate the session data with a specific user.
Now let's go through each option to understand why it is correct or incorrect:
Option A) Session.Dump - This option is incorrect. The Session class in ASP.NET does not have a Dump method. Therefore, this option is not a valid way to dump sessions.
Option B) Session.Abandon - This option is correct. The Session.Abandon method is used to abandon or end a session. When you call Session.Abandon, it destroys the session and removes all session data. This effectively "dumps" the session.
Option C) Session.Exit - This option is incorrect. The Session class in ASP.NET does not have an Exit method. Therefore, this option is not a valid way to dump sessions.
Option D) None of the Above - This option is incorrect. As explained above, the correct option is B) Session.Abandon.
Therefore, the correct answer is B) Session.Abandon. This option is correct because calling Session.Abandon will effectively dump the session by destroying it and removing all session data.
