Solution

The correct option is B connecting an inductor in series with the load
Here, current leads the voltage by a phase of $π / 4$ .
Thus unknown load is a capacitor.
The current can be brought in phase with current through it by connecting it i series with an inductor of same impedance as that of the capacitor.
