I don't know when she ---,but when she----,i -----you know.
a.comes ,will come ,let b.will come,comes ,will let c.will come ,comes ,let d.comes ,comes,let

.will come,comes ,will let 是正确的答案.
will come是宾语从句部分.comes --主将从现中的现.will let ----主将从现中的将.
再问：为什么不可以选另外的三个？另外三个是什么意思呢？谢谢
再答：因为不符合主将从现的原则，或者时态混乱。
