Two infinitely long conducting parallel rails are connected through a ...
By Faraday's Law of induction,
ε=− dϕ​/dt
=−Bl (dx/dt) ​=−Blv0​
This emf should induce the movement of charges creating a current. But due to the attached capacitor, all charges are conserved.
Thus I= dq/dt ​=0
The correct option is C.

Read the following text and answer the following questions on the basis of the same: Power factor correction capacitor Power factor correction is a method to reduce the lagging power factor in inductive loads by fixing a high value capacitor across the phase and neutral line close to the load. When the Voltage and Current are in phase with each other in an AC circuit, the energy from the source is fully converted into another form to drive the load and in this case the power factor is in unity. When the power factor drops, the system becomes less efficient. In inductive loads, current “lags'' the voltage leading to “lagging power factor”. Power factor correction is the method to reduce the lagging power factor in inductive loads by fixing a high value capacitor across the phase and neutral close to the load. These capacitors have leading power factor so that it will neutralize the lagging power factor of the load. Power capacitors are huge non polarized metal film electrolytic type capacitors. Capacitors should be sufficiently rated to the load capacity. It should be connected to the lines, only when the loads are running and drawing currentPower factor corrector capacitors should be connected
