They're based on the results of your testing.
The formula that can be applied in this problem is W = Fd
where W is work, F is the force and d is distance. You have 450N and 3m, all
you have to do is to multiply it.
W = Fd
W = (450N) (3m)
W = 1350J
The answer is letter C.
I believe that crude oil is derived from plants because it is made up of a liquid that is found beneath the earth surface so I guess you could go with plants it is not an animal or rock or salt so.. could be brainliest not 100% sure so if you are not sure go with your gut
