Correct Answer
B. 4 hours
Explanation
Recycling one aluminum can can save enough energy to keep a 100-Watt Bulb burning for 4 hours. Aluminum is a highly recyclable material, and the process of recycling it requires significantly less energy compared to producing new aluminum from raw materials. By recycling aluminum cans, we can conserve energy and reduce the need for extracting and processing new aluminum, which in turn helps in reducing greenhouse gas emissions and preserving natural resources. Therefore, recycling one aluminum can can save enough energy to power a 100-Watt Bulb for 4 hours.
