Solve the following python programming problem given the following code:
def add_test_handlers_to_daemon(daemon) : 
    def handler_for_simple(m, verb, data = None) : 
        if (verb == 'POST') : 
            assert (data == 'simple_ok') 
return 'simple_ok' 
daemon.add_json_route ('/test_simple', handler_for_simple, ['GET', 'POST']) 
    def handler_for_query(m, verb, data = None) : 
        return urlparse.urlparse (m.group (0)).query 
daemon.add_json_route ('/test_query(.*)', handler_for_query, ['GET']) 
    def handler_for_complex(m, verb, data = None) : 
        if (verb == 'POST') : 
            assert (data == 'complex_ok') 
assert (int (m.group (1)) == 2) 
        return 2 
daemon.add_json_route ('/test_complex/(\\d+)', handler_for_complex, ['GET', 'POST']) 
    def handler_for_server_exception(m, verb, data = None) : 
        raise daemon_module.SilentException ('Server side error') 
daemon.add_json_route ('/test_server_exception', handler_for_server_exception, ['GET', 'POST']) 
    def handler_for_delete(m, verb, data = None) : 
        assert (verb == 'DELETE') 
        return 'OK' 
daemon.add_json_route ('/test_delete', <MASK>, ['DELETE']) 
    def handler_for_obj(m, verb, data) : 
        x = { 
            
} 
        x ['status'] = 'OK' 
        return x 
daemon.add_json_route ('/test_dyn_obj', handler_for_obj, ['GET']) 
    def handler_for_sleep(m, verb, data) : 
        import time 
        time.sleep (0.25) 
        return 'OK' 
daemon.add_json_route ('/sleep', handler_for_sleep, ['GET']) 
    
    Given the code above, what is a proper replacement for <MASK>? Choose among: handler_for_server_exception, handler_for_complex, handler_for_simple, handler_for_sleep, daemon, handler_for_obj, handler_for_query
