In 1988, the Council onEconomic Priorities began publishing Shopping for a Better World, with thesimple thesis of consumers having the power to change companies by thesimple expedient of refusing to buy.

A.    with the simple thesis of consumers having

B.    which had the simple thesis of consumers having

C.    where the thesis was simple: consumers having

D.     with a thesis that is asimple one:  consumers have    (E)

E.    whose thesis was simple: consumers have

E正确。

关于B选项论坛的语法笔记给出的解释是thesis应该用同位语从句修饰，thesisof sb. doing sth.结构中thesis的核心只是sb.，而并不是”sb做某事”

我的疑问是 B选项如果改成 which had the simple thesis of consumers' having 的话是否正确呢？？
