你好,應(yīng)該是：
A
翻譯為 他何時為什么來這兒還不清楚.
句子的主語是whne and why he came here,是一件事
所以為單數(shù)
如果用have,應(yīng)該用被動
所以只能選A
~~~~~~~~~~～～~~~~祝你進步,如對你有幫助,請及時采納~~~~~~~~~~~~~~~~
When and why he came here () yet?A is not known B are not known C has not known D have not been
When and why he came here () yet?A is not known B are not known C has not known D have not been
