From Ohm's law,
Current(I) = Voltage(V)/Resistance(R).
Current flows only when circuit is closed.
Current(I) = Voltage(V)/Resistance(R).
Current flows only when circuit is closed.

When the circuit is open, there is no path for flow of current. If the circuit is in short condition then there is o voltage. Voltage and current both are present when a circuit is in closed condition. So closed condition is the right answer.

Current is flow of electrons and its direction is against current. Electrons flow only in closed circuits so current only will be in closed circuits.

An open circuit leads to zero current whatever be the voltage so not A,
An insulated circuit will lead to a flow of negligible current however large the voltage be, so not B,
A high change in voltage is required to influence a small current in high resistance, so C is not viable.
Thus the closed circuit in which current flows on providing a potential difference and has no restrictions of insulation or high resistance is the most viable option.

Electrons only flow in an instance where there is continuity, therefore in a closed circuit, there is flow of electrons.

The electrons flow in open circuit zero(no current) the electrons flow closed path is necessary.

When circuit well closed that time only current well flow in open circuit current does not flow?

The amount of potential energy between two points on a circuit. One point has more charge than another. This difference in charge between the two points is called voltage. Current:The flow of the river.

If the circuit is open no current flow so current flow occur only in closed circuit.
