Many population studies have linked a high-salt diet to high rates of hypertension and shown that in societies where they consume little salt, their blood pressure typically does not rise with age.

(A) shown that in societies where they consume little salt, their

(B) shown that in societies that have consumed little salt, their

(C) shown that in societies where little salt is consumed,

(D) they showed that in societies where little salt is consumed,

(E) they showed that in societies where they consume little salt, their

正确答案是C，请问B选项为什么错误？
第一，为什么societies用that从句修饰错？
第二，为什么their不能指代Societies?  这个就近指代的原则，是不是不能指代同一句子中的介词连接的名词？例如in+N.?那么还有哪些结构不能用代词指代呢？

我個人認為，THAT定SOCIETIES，那麼就是說是society consumes the salt,this is weird since it is the people who consume solt,so B is incorrect.
LZ說THEIR指代SOCIETY，那麼就是說SOCIETY的BLOOD PRESSURE?是不是不符合邏輯~
it is just my opinion~
