In the purely inductive circuit, during the first quarter cycle, the power supplied by the source is stored in the magnetic field set up around the coil. In the next quarter cycle, the magnetic field diminishes, and the power stored in the first quarter cycle is returned to the source.
Hence, the correct option is (C)

Pure Inductive Circuit
A pure inductive circuit is a type of electrical circuit that consists of only inductive components, such as inductors or coils. It does not contain any resistive or capacitive elements. In such a circuit, the current and voltage are out of phase by 90 degrees. This means that the current lags behind the voltage.
Power Consumption in a Pure Inductive Circuit
a) Consumers some power on average
In a pure inductive circuit, there is no power dissipation due to resistance. However, it does consume some power on average. This is because the inductor stores energy during one part of the cycle and releases it back to the circuit during another part of the cycle. Therefore, although there is no net power consumption, there is a transfer of energy between the inductor and the circuit.
Power Flow in a Pure Inductive Circuit
c) Takes power from the line during some part of the cycle and then returns back to it during other parts of the cycle
During the positive half-cycle of the alternating current (AC), the voltage across the inductor increases, causing the inductor to store energy in its magnetic field. As a result, the inductor takes power from the line during this part of the cycle.
During the negative half-cycle of the AC, the voltage across the inductor decreases, causing the inductor to release the stored energy back to the circuit. This results in the inductor returning power back to the line during this part of the cycle.
Therefore, a pure inductive circuit takes power from the line during some part of the cycle and then returns it back to the line during other parts of the cycle.
Conclusion
In summary, a pure inductive circuit consumes some power on average, even though it does not dissipate any power due to resistance. It takes power from the line during one part of the cycle and returns it back to the line during other parts of the cycle. This power transfer is a result of the energy storage and release in the inductor.
