I gave my students this multiple choice question: What do the energy resources uranium and coal have in common?

Only one answer is correct among these 4 choices:
- They both are formed from the remains of dead organisms.
- They both are acquired by mining the lithosphere.
- They both release energy through combustion.
- They both generate radioactive wastes.

Could you tell me which one is correct?
