I beleive the answer would be B: Buring fuel
The way how fossil fuels could be used wisely is through a careful planning strategy where we would include and think about the possible distribution methods of fossil fuels around the world for nations which cannot afford and use renewable energy sources. Moreover, they would be more wisely used when less of them would be used for daily needs and when massive companies would transition to renewable energy sources.
The awnser is D
hope that helped!
