announced that since sales of up to one-fourth of its

A. that since sales of up to one-fourth of its stores

are poor, they will be closed.

B. it is closing up to one-fourth of its stores, which

accounted for its poor sales

C. it was closing up to one fourth of its stores

because of poor sales.

one-fourth of its stores.

这道题答案是C

但是宾语从句的that不是不能省略么？

A的they没有指代对象，应该指代stores，但是这里语法上不行，因为是修饰成分

B,C没有that

E having , such that都不对

所以当时就选了D，但是用进行时态好像不太好。

请讨论。
