Correct Option: B
Here's how to solve the problem:
1. Convert power to kW: The refrigerator uses 150W, which is equal to 150/1000 = 0.15 kW.
2. Calculate energy consumption: Energy consumption is calculated using the formula: Energy (kWh) = Power (kW) * Time (hours).
3. Plug in the values: Energy = 0.15 kW * 336 hours = 50.4 kWh.
