To answer this question, we need to understand how sessions and scopes work in web applications.
When a user opens a JSP page, a session is created for that user. The session allows the server to store and retrieve information specific to that user throughout their browsing session.
In this scenario, when the user clicks on the button and a new window opens, the session is still valid in the new window. This means that the server can still access and retrieve the session data for that user.
On the other hand, scopes in JSP refer to the lifespan and visibility of variables within a JSP page. The most commonly used scopes are request, session, and application. These scopes determine how long a variable will exist and be accessible within a JSP page.
However, the scope of variables does not directly affect the validity of the session in the new window. The session remains valid regardless of the scope of variables used in the JSP page.
Therefore, the correct answer is B) The Session is valid in the new Window.
