If a stepper motor has 4leads or wires comming out of it, its commonly known as BIPOLAR stepper motor. Unipolar stepper motor has five leads comming out of it. The difference between unipolar and bipolar stepper motors is common point or nuetral which present incase of unipolar stepper motor. We can distinguish them by measuring the resistance between the leads

Answer: option B
