对于OG12 132的理解，请高手指点

132. Although the term "psychopath" is popularly applied to an especially brutal criminal, in psychology it is someone who is apparently incapable of feeling compassion or the pangs of conscience.
(A)  it is someone who is
(B)  it is a person
(C)  they are people who are
(D)  it refers to someone who is
(E)  it is in reference to people
答案是D，关于E中解释说缺动词，又结合原来薰衣紫草mm说的“term自己怎么可以澄清要说的东西, 必然是被引用来说明.”，现在得到自己的一些想法：in reference to是个介词短语，不含动作成分，is在这里不是主系表结构的用法，只是表示被动，而真正的动词没有出现。不知这样理解是否正确啊？

OG说应该用it used in reference to people更好些，如果一定要用in reference to的话，is当然是动词，只是在这里意思用的不对

OG里是说用it is used in reference to啊，那么is就不是动词，而表被动
