The correct answer is D) the stop button contacts, the "B1" contacts, the "M" contacts, the "M" coil and the "OL" contacts. This is the correct answer because when the motor is started by the controller shown in figure "C" of the illustration, the holding current flow path through the control circuit while the motor is in operation includes the stop button contacts, the "B1" contacts, the "M" contacts, the "M" coil, and the "OL" contacts. These components are responsible for maintaining the motor's operation once it has been started. The other answer choices are incorrect because they do not accurately represent the complete holding current flow path through the control circuit. For example, options A and B are missing the "M" contacts, while option C is missing the "B1" contacts.
