A Correct answer
Explanation

To receive the HttpServletRequest instance in a Struts 2 Action class, you implement the ServletRequestAware interface. This interface's setServletRequest(HttpServletRequest) method is called by Struts 2 before the action executes, injecting the request object. ServletResponseAware is for responses, ActionSupport is a convenience base class.
