Answer 1

Correct option is (b) 1 and 0 The best I can explain: We know that, power factor is maximum and equal to 1 for a purely resistive load. Power factor is minimum and equal to zero for a purely reactive load. Hence, in an AC circuit, the maximum and minimum values of power factor are 1 and 0 respectively.
