(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）
(E) with a history of high blood pressure running in their family
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
