Right answer is (b) power consumption and time duration

Explanation: An electronic energy meter is used in two stages. Energy measurement basically involves the measurement of power and the time duration. In the first stage, it is used as a wattmeter while in the second stage it is used monitoring the power consumed in a time interval.
