Current flow always in a closed circuit.
For eg:
If you have two Wire and a lamp.
Then both wire first terminal you connect to the lamp and second terminal you connect only one wire. Then the lamp can't blow.
The reason is the circuit is not complete.
And again we connected both wires then lamp give light.
So the flow of current is important to close the circuit.

No, the Current dose not flow in an open circuit.

Open circuit - Voltage will occurred.
Close circuit - Current will occurred,
Close circuit - Current will occurred,

Switch is open means the circuit incomplete. Switch is close means the circuit complete and the current always flow in a close path/circuit.
So option B is the answer.
So option B is the answer.

To flow of current there should be closed circuit so switch should be closed.

Current always flows, when there is some closed system.

A switch is open means circuit not completed. So, current not flow the circuit. But, the switch is close means circuit complete. So, current flow easily the circuit. So answer option B.

When circuit is open then we can say the wire of system is cut at anywhere so there is no voltage transfer here so option B is correct answer.

We know v=ir, if v=0 [as per question] then definitely i=0. i.e no current flow through circuit.
Secondly if we consider this is a circuit which is closed i.e. [] then current will flow.
But if we consider circuit is open i.e [ ] no current flow.
So option B will be answer.
