A．they both B．which both C．both of them D．both of which
--
为什么不选B？
答案是D.

Answer 1

1. 答案是D.
both of which are being built in my hometown
=both of the two schools are being built in my hometown

2. 答案B只错在both的位置上。
both做状语时，一般是放在be动词之后的。
所以应该是：which are both being built in my hometown

Answer 2

恩…both...不能这么用，它只能放在正常的代词后面，做同位语…而which...就是一引导词…没法同位修饰……楼主背下来D的用法就好了
