Unlike the original NationalMuseumof Science and Technology in Italy, where the models are encased in glass or operated only by staff members, the Virtual Leonardo Project, an online version of the museum, encourages visitors to "touch" each exhibit, which thereby activates the animated functions of the piece.
(A) exhibit, which thereby activates
(B) exhibit, in turn an activation of
(C) exhibit, and it will activate
(D) exhibit and thereby activate
(E) exhibit which, as a result, activates

答案上说 which 没有先行词，请问用which指代“exhibit”是否可以？
还有就是C 为什么不对？为什么说IT没有先行词？把exhibit当先行词或者是把Virtual Leonardo Project当先行词不可以吗？

小白出国

我认为which是指代exhibit，但是和activate不符合逻辑。it 应该代指project,但是同样不符合逻辑。
感觉这里and 有顺接的意思， 似乎是，I eat the dinner and go to bed. 似乎是这种意思。但是我不确定，等待NN正解。

which如果指代exhibit的话，代入变成 exhibit  activates the animated functions of the piece  -->展览activate那些functions？逻辑不make sense
把exhibit或者Virtual Leonardo Project代入it得出和上一行一样的问题：逻辑不make sense
