• B. time
• C. mass
• D. power

Hint:

Answer 1

The Correct Option is A

The kilowatt-hour (kWh) is a unit of energy, commonly used to measure electrical energy consumption.
\[ 1 \text{ kWh} = 1000 \text{ W} \times 3600 \text{ s} = 3.6 \times 10^6 \text{ J}. \] Thus, the correct answer is \( \mathbf{(A) \text{energy}} \).
