Solution

The correct option is C Voltmeter
EMF of a cell or battery is the total voltage or potential difference developed between the two terminals of the cell/battery when the two terminals are in open circuit condition.
Terminal Voltage of a cell or battery is the potential difference build between the two terminals of the cell/battery or load when a load is connected to the cell or battery or when a current is being drawn from the cell or battery.
Voltmeter is used to measure both depending upon the state of connected batttery or cell.
