请教一道逻辑题

Not all life depends on energy from sunlight.Microbial life has been found in bedrock more than 5km below the surface of the earth,and the bacteria have been found on the deep ocean floor feeding on hydrogen and other gases rising from the interior of the earth through vents in the ocean floor.

The statements above,if true,best support which of the following as a conclusion?

E.finding bacterial remains in coal and oil would establish that the bacteria had been feeding on substances that hadn't been produced from the energy of sunlight.

答案上说该选项错在结论里不应该只有bacteria还应该有microbial，我觉得是原文中讲的关于bacteria的生活环境是deeo ocean floor和选项里的coal以及oil无关，所以是视为无关选项，各位怎么看待，谢谢。

E is not a good conclusion b/c coal and oil are from trees, which lived by using sun energy millions of years ago.
