The switch is a simple device used to either break the electric circuit or complete it. The most common form of the electric power switch is a basic manual electromechanical unit.
A switch is said to be in ON position when it makes or completes the circuit and allows the current to pass through.
Similarly, a switch is in an OFF position when it breaks the circuit and does not allow the current to pass through.
For using electric gadgets/ appliances/ circuit, we have to turn the switch in ON position. Therefore, precaution given in option (d) need not be considered.
