Power consumed in an AC circuit becomes zero if
A Inductance and resistance are both high.
B inductance and resistance are both low.
C inductance is very high and resistance is negligible.
D inductance is low and resistance is high.

The correct option is C inductance is very high and resistance is negligible.
The power consumption in an AC circuit is zero when the circuit contains only inductance or capacitance since the average power consumed in a cycle is zero for inductance or capacitance. Hence, for the given options when the inductance is very high and resistance is negligible, then power consumed is zero. Here, inductance can be of any value.
