These meterials can be used to conduct,______lead,electricity from place to place.
A.particularly
B.or
C.chiefly
D.of
这是同位语从句.想知道为什么,of为何不可,of和or引导同位语从句有什么区别啊?

首先,同位语最重要的是,两个东西其实指代的是同个事物.举个例子Lily,my best friend, is the monitor of our class.这里的lily和my best friend就是同位语关系.
其次,我们来分析这个句子的意思“这些材料用来将电流从一个地方引导到另一个地方（可以意译为“传输”）
再次,我们来分析conduct和lead这两个单词,他们都是“引导”的意思,都是动词,作谓语,那么,在句子中连接两个动词用什么词呢?“and”或者“or”,表示他们地位相同.而of后面一般接名词.而这里只是同一个说法换一个单词,所以不能用“and”,而要用“or”,表示这种或者那种引导.
再次,一般来说同位语是个句子才叫同位语从句,一般用that,whether,连接副词 how,when,where等引导,这个地方只是同位语,不是从句.
最后,建议你到网上查查同位语是怎么回事,加深印象.
