When components are used to perform the function of stop, they are generally wired as normally closed and connected in series with the motor starter coil. This means that the circuit is normally closed to allow motor operation, but when the stop button is pressed, the circuit is opened and the motor stops. This is the most common and safe wiring configuration for a stop function. When components are used for a stop function, they need to be normally closed to allow the circuit to be closed when stop is required. The components must also be wired in series with the motor starter coil since a break in any of the components will break the circuit and stop the motor. Therefore, the correct choice is normally closed and connected in series, which is option B.
