求助一道GWD的题

关灵韶

Several financial officers of the company spoke on condition that they not be named in the press reports.

A.      that they not be named

B.      that their names will not be used

C.      that their names are not used

D.      of not having their names

E.       of not naming them

 答案是A  初看这道题觉得那个都不对 我只能断定答案在ABC中 后来我选了C

我不不明白A为什么对   我猜想这里是有一个省略 可是省略了什么 凭借什么省略的呢

希望大家帮帮忙

省略了should,虚拟语气！
