OG71关于it的指代问题

茉莉蔷薇

71.Unliketheoriginal 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 activatesthe 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

答案是D，想问一下这里有关“it”的用法，OG解释是“there is no antecedent for it because touch is a verb”

It 为什么不能指代the Virtual Leonardo Project

是这样，语法与逻辑不一致是错误的选项，你认为it指代那个是语法，但是逻辑上不是应该是touch引发的激活，而且这换句话是指代歧义

crack的意思是说语法上虽然可以，但是这里逻辑的意思应该是说由于touch才会activate，是么？
那这个指代歧义是神马意思？
