Correct Answer

Explanation

The instrument that can measure both AC (alternating current) and DC (direct current) is called a "multimeter." A multimeter, also known as a VOM (volt-ohm-milliammeter), is a versatile electrical and electronic test instrument that can measure various electrical parameters, including voltage, current, resistance, and often other properties like frequency and capacitance. It's an essential tool for anyone working with electrical circuits and systems because it can handle both AC and DC measurements.
