有下面题目不太明白，请帮忙，由于马上就考试了，复习进展缓慢，着急ING

1.Several financial officers of the company spoke on condition (that they not be named) in the oress 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

问正确答案和原因，谢谢（括号内为划线部分）

答案A。从spoke看出从句只能是过去时，排除bc；d、e答案短语中的主语不清，排除。on condition that 是固定搭配，意思“假如；根据……的条件”。
