请教OG11版黄书SC复习部分第5题？

As its sales of computer products have surpassed those of measuring instruments, the company has become increasingly willing to compete for the mass market sales (they would in the past have concede to rivals.)

A.they would in the past have conceded to rivals

B.they would have conceded previously to their rivals

C.that in the past would have been conceded previously to rivals

D.it previously would have conceded to rivals in the past

E.it would in the past have conceded to rivals

括号为画线部分，答案E。我也觉得E是最对的，但它不是犯了一个大忌，宾语从句（这个是吗？还是同位语从句呢？）后面一定要跟that吗？我觉得it前面一定要加连接词(如that)才对啊？请牛牛指导！

定语从句省略that
