I gave my students this multiple choice question: Oil, coal, and natural gas are fossil fuels formed under what conditions?

Only one answer is correct among these 4 choices:
- low temperature and high pressure
- high temperature and high pressure
- low temperature and low pressure
- high temperature and low pressure

Could you tell me which one is correct?

high temperature and high pressure
