Answer : The correct option is, increase the potential of charges in the circuit.
Explanation :
Battery : It is an electrical device which consists one or more electrochemical cells with an external connection provides to power electrical devices.
When the battery supplying an electrical power or current then its positive terminal is the cathode and its negative terminal is the anode.
The function of battery in the circuit is that the battery is the source of energy that provides the voltage of energy to get the current flowing in a circuit. Or we can say that it increases the potential of charges in the circuit.
Hence, the correct option is, increase the potential of charges in the circuit.
