In 1988, the Council on Economic Priorities began publishing Shopping for a Better World, with the simple thesis of consumers having the power to change companies by the simple 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 a simple one:  consumers have

E. whose thesis was simple:  consumers have

B为什么不正确呢，是因为of后面动名词不应该有独立主格吗？
