The last statement just talks about volume of hydrocarbons - but what if with the same volume the oil that you can extract is still different?
I read it as
Buried animals - hydrocarbons - chemical transformation - oil
The statement is implying
Buried animals - hydrocarbons - chemical transformation - hydrocarbons
How did we connect the oil link here?

Hi Kavicogsci,
The original one is:
{Hydrocarbons derived from organisms buried under ancient sea} → Chemical transformations → Oil
The new ("suppose") mechanism is:
{Other complex hydrocarbons trapped within the Earth} → Bacterial action → Oil
And because this is a strengthen question, we try not to assume that extraction ratios are different (we have no reason to believe that there is a difference between the two kinds of oil, depth etc.). Remember that the correct option just needs to strengthen. It doesn't need to be perfect.

Hi experts GMATNinja KarishmaB IanStewart
Is option D wrong because of the following reasoning?
"The only bacteria yet found in oil reserves could have leaked down drill holes from surface contaminants" gives an indication that bacteria went down below the earth because of human activity and not because of nature or its existence since last thousand/millions of years. The formation of oil takes at least thousand of years, thus, going down of bacteria because of human activities decreases our confidence in the conclusion that the oil reserves are higher because of bacterial action. Please correct me if I am wrong.
