In flap-up configuration, what is the maximum positive load factor?

The main concept is the airframe’s limit load in a given configuration. The maximum positive load factor is the highest “g” the airplane is certified to withstand during normal use, which is the stress the structure can safely handle in flight when you’re pulling up. In flap-up configuration, the published design limit for the positive load factor is +3.1 g (with the corresponding negative limit around -1.24 g). This means you should not exceed about 3.1 g during maneuvers with the flaps retracted, or you risk structural damage. The flap setting changes lift distribution and stress paths in the wing, so the limit loads are specified for each configuration. Other options don’t match the flap-up data because they propose higher or lower positive limits (or a different negative limit) than what the aircraft is certified to tolerate in this configuration.
