What exception cannot be handled with rescue_from method in application controller? e.g class ApplicationController < ActionController::Base rescue_from Exception, with: error_handler . . . . . . . . . . end

1). server errors 2). record not found (404) 3). routing errors 4). all of these

Thanks in advance

If you want help with your school work you should at least rephrase the question so it is not quite so obvious.
