大家给我理一理~选E,但是内心纠结

Most geologists believe oil results from chemical transformations of hydrocarbons derived from organisms buried under ancient seas. Suppose, instead, that oil actually results from bacterial action on other complex hydrocarbons that are trapped within the Earth. As is well known, the volume of these hydrocarbons exceeds that of buried organisms. Therefore, our oil reserves would be greater than most geologists believe.
Which of the following, if true, gives the strongest support to the argument above about our oil reserves?C
(A) Most geologists think optimistically about the Earth’s reserves of oil.
(B) Most geologists have performed accurate chemical analyses on previously discovered oil reserves.
(C) Ancient seas are buried within the Earth at many places where fossils are abundant.
(D) The only bacteria yet found in oil reserves could have leaked down drill holes from surface contaminants.
(E) Chemical transformations reduce the volume of buried hydrocarbons derived from organisms by roughly the same proportion as bacterial action reduces the volume of other complex hydrocarbons.

(E) Chemical transformations reduce the volume of buried hydrocarbons derived from organisms by roughly the same proportion as bacterial action reduces the volume of other complex hydrocarbons.

举例说明吧，buried hydrocarbon有 5千克，chemical transformation reuduce 了 10%，结果形成了4.5千克oil
                    other complex hydrocarbons 有50千克(题目中说了，储量丰富）， bacteria action reduce了相同的比例，10%，结果形成了，45千克oil。这样不就support argument了吗？
