Freedman’s survey showed that people living in small towns and rural areas consider themselves no happier than do people living in big cities.

(A) no happier than do people living

(B) not any happier than do people living

(C) not any happier than do people who live

(D) no happier than are people who are living（A）

(E) not as happy as are people who live

我个人认为选d或e比较好,给出的答案是a,a中的do 无法还原，找不到合理的动词对象
