It has something to do with the part electricity___in our li

不看意思 直接选B
句子结构分析 It has something to do (with the part electricity)
这里已经有了has作谓语 一个主句就一个谓语
那选项里4个动词 能符合非谓语动词的就是B
还原回去：It has something to do with the part electricity played in our life
也就是It has something to do with the part electricity which was played in our life
请记住 非谓语动词（ing和ed）前者是主动 后者是被动 实际上2者就是个从句的作用 只是让你句子看起来简洁

D
定语从句用的短语是play ....part in... 在。。。。中起着。。。。作用
【that/which】electricity【plays】in our life.是省去的关系代词 that 或者which 引导的定语从句，修饰先行词part

全句意为：
这个和电在我们的生活中所起的作用有关。

Choose D. the meaning of sentence above is electricity plays an important role in our life that must be relative with.
part role, 表示角色，一般现在时,省去that.
