Yes, because open circuit not supply completely and disconnect component Or closed circuit easily flow of current, component are Ok.

Current must be flow in short circuit or closed circuit only.

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

Current is always flow in a closed circuit only.

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

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.

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.

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.

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

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.
