Switching off a fan in an empty room is an example of what?

Answer and explanation

Correct answer: Energy conservation

A fan running in an empty room provides no useful service, so switching it off prevents unnecessary electricity consumption. This action is therefore an example of energy conservation, making option A correct. Energy conservation means using less energy by avoiding waste and operating appliances only when they are needed. Waste generation concerns the production of discarded materials, water pollution concerns contamination of water, and excessive plastic use concerns unnecessary plastic consumption. None of those processes is described here. The key reasoning is that turning off an unused appliance saves electricity and reduces avoidable resource use.
