Solution

The correct option is A

volt


There must be a potential difference to keep a current flowing through a conductor. This potential difference is provided by a battery in a circuit.

The electromotive force is the potential difference between two terminals of the battery when no current is drawn from it.

It is measured in the unit of volt.
