Answer 2

Oil and Gas result from:

4.) The decay of tiny marine organisms accumulated on the ocean floor millions of years ago.

Why?
These organisms fell to the ocean floor millions of years ago and and are being made up right now. Oil and gas are both non renewable, because it takes time for the earth to replenish its supply.

Hope I helped you out!
