Solution : The correct answer is (B) Charcoal
Non-commercial energy sources are typically traditional or non-market-based energy sources that are often used in rural or subsistence settings. They are not commonly bought or sold in commercial markets. These energy sources are often locally available and may include biomass, animal dung, wood, and other traditional fuels.
Charcoal is considered a non-commercial energy source as it is often produced locally through traditional methods and used for cooking and heating in rural and informal settings. Charcoal is typically not widely traded in commercial markets, and its production and use are often informal and localized.
