Question

Crude oil is delivered from which of the following materials?

A. Marine organisms
B. Plants
C.Rocks
D.Salts

Answer 1

I believe the answer is A, because we derive oil from ancient organisms such as algae and plankton. So it seems that A makes the most sense in this situation. 

Answer 2

 I believe it's B because both plants and animals decay into crude oil.
   Years ago animals and plants died and later fell to the bottom of the sea.

 Hope this helps! Mark brainliest please.
