Answer

Brief Explanations:

A voltmeter is specifically designed to measure the potential difference (voltage) between two points in an electrical circuit. An ammeter measures current, a potentiometer is used for measuring emf or comparing voltages in a more complex setup, a galvanometer detects small - scale electric currents, and there is no standard device called a batterymeter.

Answer:

C. voltmeter
