The correct option is (c) Measure quality factor of capacitor and inductor
The best I can explain: Q-Meters are intended to measure the quality factor of a capacitor and inductor. Q = \(\frac{Lω}{R} = \frac{1}{ωCR} = \frac{V_C}{V_A}\). They are not used for measuring capacitances and inductances, unlike AC Bridges.
