If the circuit is open, then no current flows, and none of the devices does anything. They all just lay there, stone cold.

Answer: The correct option is A.

Explanation:

In the given problem, a light bulb, a fan, and a tiny speaker are connected to a battery in a series circuit. But the circuit is open.

The battery forces the electrons to flow in the circuit. The rate of flow of electrons constitutes the current. But the battery is not on. Then , the current will not flow in the circuit.
