Such electronic device __ are used in a radio set are also found in a computer.
A in which B that C which D as

我的错误见解是，这个是定语从句，从句部分缺主语且先行词是物，所以是which

搞不懂不想睡觉

我感觉选as应该把后面的are去掉

Cuz she wants the D

为什么我也选c

这个句子读着头皮发麻

as引导限制性定语从句常用于such...as, the same...as, so..as等结构中。。

谁出的烂题？

Such ...as啊。。

你要选which的话that完全也可以
