HELP！OG15 SC73 如何判断动作发出者的问题

大鸽子

73. Unlike the original National Museum of 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
OG的解释是这样的——It makes more sense tomake the visitors the agents responsible for the action of both the verbs—touch and activate.
                 C的解释——C There is no antecedent for it because touch is a verb.
                 D的解释——D Correct. The agent of the action is clearly indicated by the grammatical structure of the sentence; visitors are encouraged to “touch” … and thereby (to)activate.
                 OG同时OG还指出A，E的which是没有先行词的.
私以为，前半句的结构为——Unlike A, B encourages visitors to "touch" each exhibit, blabla...
             而AE的错误原因在于which错误修饰Project，而s+verb+o,which的结构，which是不能修饰S的。
                 那么C选项中的it和D选项中activate的动作发出者，为什么不能为Project呢？？？？

                百思不得其解君食不知味夜不能寐临表涕零，，，不知所云，求各位指教啦~
                谢谢大家啦~~

那跳的也太多了吧。。而且从语意上来看，project activate了什么什么function也不太合适，project本身不能去activate吧，应该是visitors通过touch这个展览品从而activate了这个展览品的功能

activate的动作发出者应该是visitors吧，或者说visitors的touch这个动作

不应该是porject encourage..... and activate?? 好吧，这里主谓一致不对。。。
那可不可以A选项 which跳跃修饰 Project呢？？
