大全sec关于it的用法

In the traditional Japanese household, most clothing could be packed flatly, and so it was not necessary to have elaborate closet facilities.

(A) flatly, and so it was not necessary to have elaborate closet facilities

(B) flat, and so elaborate closet facilities were unnecessary

(C) flatly, and so there was no necessity for elaborate closet facilities

(D) flat, there being no necessity for elaborate closet facilities

(E) flatly, as no elaborate closet facilities were necessary

请问这里的A和B的区别在哪里？为什么我感觉都对呢？

flatly修饰be packed，"平坦着打包衣服" 说不通，flat应该修饰clothing ，“衣服被打包得平坦的”，所以要用形容词形式。

用elaborately修饰pack这个动作倒是可以。
