SOS 求助一道SC，大NN请进

cls99

这是Magoosh上面的一道题：

The term "cult" has no formal definition in the Study of Religions, but in the popular media, it is a group of people that uses manipulative techniques to brainwash unsuspecting victims.
A. it is a group of people that uses
B. it is a group of people that use
C. they are a group of people who use
D. it refers to a group that uses
E. it is a term in reference to a group of people known to use

OA: D

可以排除A、C、E，当时选了B。

想问下B的错误在哪？以及D中a group与Choice A的a group of people差别在哪？谢谢！！！

关键点应该不是group和group of people之间的差别 而是 it is 和 it refers

it 指的是 the term cult， 显然不能是a group of people， 只能refer to something 或者 E， 这样排除了 A B C ，E太罗嗦 D最佳
