B,D Correct answer
Explanation

The doGet() method in HttpServlet explicitly declares ServletException and IOException in its method signature. ServletException is thrown for servlet-specific errors, while IOException handles general I/O errors during request processing. NullPointerException (unchecked) and FileNotFoundException (not thrown by doGet) are not declared exceptions.
