AI Explanation

To answer this question, you need to understand the classes in Java Servlet API that are related to handling HTTP requests and responses.

The correct answer is A) HttpServletRequest. This class includes the getSession method that is used to get the HttpSession object.

Option A) HttpServletRequest - This option is correct because the HttpServletRequest class is part of the Java Servlet API and provides methods to handle HTTP requests. It includes the getSession method, which returns the HttpSession object associated with the request.

Option B) HttpServletResponse - This option is incorrect because the HttpServletResponse class is used to handle HTTP responses, not requests. It does not include the getSession method.

Option C) SessionContext - This option is incorrect. The SessionContext interface is part of the Enterprise JavaBeans (EJB) API and is used to manage EJB sessions, not HTTP sessions.

Option D) SessionConfig - This option is incorrect. There is no standard Java Servlet API class named SessionConfig.
