The power factor can vary between definite limits, being 1 (unity) for purely resistive circuits, where the phase angle is 0° and P = UI; or 0 for purely reactive (inductive or capacitance) circuits, where the phase angle is 90° and P = 0.
purely inductive circuit it required more reactive power, therefore, power comes zero.
Power factor=true power/apparent power.
Apparent power=true power+ reactive power.
So, the power factor is inversely propositional to reactive power.

The question is asking for power factor not for angle.
cos(phi) = p.f.
So, cos(-90) = 0.
Therefore answer is zero.
cos(phi) = p.f.
So, cos(-90) = 0.
Therefore answer is zero.

Circuit which acts inductively has lagging power factor. How it comes out to be zero?
