Answer:
The correct answer is option C, can eventually be used up
Step-by-step explanation:
Nonrenewable energy sources are those resources which if once used cannot be re used again.
For example – Coal, petroleum(petrol & diesel), fossils, natural gas etc.
These resources cannot be replenished if once they are consumed as they take millions of year to form.
Also all these resources are made up of hydrocarbons thus they produce polluting gases on burning except natural gas.
