Explanation: In an AC circuit, an AC voltmeter measures the Root Mean Square (RMS) voltage, and an AC ammeter measures the RMS current. The mathematical product of these two readings (V_RMS × I_RMS) is defined as **apparent power**. This value represents the total power that *appears* to be delivered by the source and is measured in Volt-Amperes (VA). It is called "apparent" because it does not account for the phase difference that can exist between the voltage and current waveforms in circuits containing reactive components (inductors or capacitors). Only the portion of apparent power that is "in phase" with the voltage actually performs work and is known as "real power" or "true power," measured in Watts. Option A, "Reverse power," refers to power flowing back towards the source, which is a different concept. Option C, "Current power," is not a standard electrical term. Therefore, apparent power (B) is the correct term for the product of AC voltage and current readings.
