(C) and a history of high blood pressure runs in the family

(D) whose families have a history of high blood pressure running in them（B）

I choose E or C. But the answer is B.

But B seems not parallel. Why?

Let me explain this myself.

A and C 都是一样的错误, 即出现了第二个主谓   families have /runs

所以可以排除

E的话, 我觉得如果用了with就不需要再又running了

谢谢dingxiang! "A and C 都是一样的错误, 即出现了第二个主谓   families have /runs " - Good point!
