1. Under the restructuring, the huge organization that operates the company’s basic businesses will be divided into five groups, each with its own executive.

(A) each with its own executive

(B) all having their own executive

(C) each having their own executive

(D) with its own executive for each（A）

(E) every one with an executive of their own

大全注释上面说A是个独立这个，可each引导的独立主格有这么加with的吗？好像从来没有见过阿，我选B，我觉得B是个独立这个的样子，为什么不对呢？

谢谢！
