Explanation:

An oscilloscope is an instrument that graphically displays electrical signals and shows how those signals change over time. It is mainly used to measure voltage - the potential difference between two points in an electrical circuit. Resistance is measured by an ohmmeter, current by an ammeter, and power is calculated from voltage and current values using formulas.

Answer:

C. Voltage
