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

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.

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.

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

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.

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.

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.

Current only flow on short circuit only it will be work on closed circuit.
