The actual cut-in pressure of the governor is the pressure at which the compressor is allowed to restart after the air pressure in the system drops below the cut-out pressure. This is an important aspect in regulating the air pressure in a system as it ensures that the system maintains a minimum pressure level. Options A, B, and D are not correct because they are less than the correct cut-in pressure of 100 psi. Choosing any of these options would result in a lower air pressure in the system which can lead to malfunction or failure of the equipment. Therefore, the actual cut-in pressure of the governor should never be less than 100 psi to ensure the proper functioning of the system.
