这要看你的语境.
但我感觉,应该是：
Do you know where she has gone --------这强调go的结果.
Do you know where she went?-------应该改写成 Do you know where she went yesterday -------需要加上go发生的确切时间.
------这一切都需要你的语感去理解.我只能说这麼多.

或者是对的

对的

后面的一句是对的
因为问话是是问对方现在知不知道她之前去哪里了
所以主句是一般现在时态，从句是一般过去时态

do you know where she went 这个是现在问她过去去哪里了，Did you know where she went? 这个是问当时（过去）知道她去哪了，2个句子都对，就看想表达什么意思了。
