(A) in a bitter dispute over

(B) over bitterly disputing

(C) after there was a bitter dispute over

(D) after having bitterly disputed about（A）

(E) over a bitter dispute about

A 是固定用法吗？berak .... in...??? 有没有dispute about 的用法？我记得有对吗？

 in 和break 没有关系，in + a bitter dispute

dispute作为名词时:a : verbal controversy : DEBATE b : QUARREL 我们可以使用a

dispute about sth.

但当dispute 作为VI ：to engage in argument : DEBATE; especially : to argue

irritably or with irritating persistence

我们一般使用dispute over sth

I pick A too.

but, what's wrong with E ??
