Answer :
Final answer:
The energy consumption of a 100-watt light bulb is 200 Wh per day.
Explanation:
The energy consumption of a 100-watt light bulb can be calculated by multiplying its power rating by the time it is on. In this case, the light bulb is on for 2 hours a day, so the energy consumption can be calculated as follows:
Energy consumption = Power × Time = 100W × 2 hours = 200 watt-hours (Wh)
Therefore, the light bulb consumes 200 Wh of energy per day, which means the correct answer is option B) 200 Wh.
