The discovery that Earth's inner core rotates independently of and more quickly than Earth's outer layers is responsible for advancing studies of the flow of heat from the inner through the outer planet and of the formation and periodic reversal in direction of Earth's magnetic field.


A.core rotates independently of and more quickly than Earth's outer layers is responsible for advancing studies of the flow of heat from the inner through the outer planet and of the formation and periodic reversal in direction of Earth's magnetic field √

B.core rotates independently of and more quickly than Earth's outer layers is responsible for advancing studies of how heat from the inner core flows through the outer planet, and the formation and periodic reversal in direction of Earth's magnetic field
", and”表示2个句子平行，and后并非是一个句子，错！

C.core rotates independently and more quickly than Earth's outer layers are responsible for advancing studies of how heat from the inner core flows through the outer planet, and how Earth's magnetic field forms and the periodic reversal of its direction  主语是discovery，谓语动词应单数，错！

D.core, rotating independently and more quickly than Earth's outer layers, are responsible for advancing studies of the flow of heat from the inner through the outer planet, and the formation and periodic reversal in direction of Earth's magnetic field  同上，且and找不到平行

E.core, rotating independently of and more quickly than Earth's outer layers, is responsible for advancing studies of the flow of heat from the inner through the outer planet and of how Earth's magnetic field forms and the periodic reversal of its direction   is在语法上应该是discovery的谓语，但是在这个选项中是core的谓语，这样句子结构就变成了：the discovery that the core is responsible for....,句子意思扭曲不说，正个句子里主语discovery跟本没有谓语动词，就是n.+从句。

句子结构：
The discovery that the core rotates... is responsible for studies of... and of...   主谓一致，平行结构
