请详细解释一下。。
＿＿＿several times about it, but he could not give the correct answer.

A. Being asked B. Having been asked

C. He would ask D. He had been asked
应该选什么，为什么？？？？

Answer 1

答案是B.have been asked,
1.整体分析，为被动，可以删除C选项，
2.进一步分析，___several times about it 和but he could not give the correct answer的主语都是he,又该句子是独立主格结构，前面的主语He可以省略，所以D选项可以删除.
3.整个句子翻译出来是“虽然他被问过很多遍了，但是他还是不能给出正确的答案”，前半句影响到后半句，所以必须使用现在完成时。
4.所以最终答案选B. have been asked.
