Correct answer is "Local variables" & "Request variables". Servlet request object is accessed by only one thread because container creates a new ServletRequest object for each request it receives. Since only one thread service the request at any time, request scope is thread safe and so are variables there in. ( Assuming we are no creating threads in doXXX() methods ).
