B
$3.6 \times 10^3\text{ J}$
C
$10^3\text{ J}$
D
$10^5\text{ J}$
Official Solution & Explanation:
Correct Answer: Option A($3.6 \times 10^6\text{ J}$)
$$1\text{ किलोवॉट घंटा} = 1\text{ kW} \times 1\text{ h} = 1000\text{ J/s} \times 3600\text{ s} = 3.6 \times 10^6\text{ Joule}$$
$$1\text{ kWh} = 1000\text{ W} \times 3600\text{ s} = 3.6 \times 10^6\text{ J}$$
