(A) they的指代对象错误;or连接的并列结构不平行。
(B) they的指代对象不清楚;副词insufficiently修饰动词consume，与原句形容词insufficient修饰对象不同，改变了原句要表达的意思。
(C) 被动语态的表达方式不清楚，没有说明施动对象;or having没有平行对象，因为前面是are consumed。
(D) who引导的并列定语从句错误地修饰紧临的名词countries。
(E) 正确，宾语从句谓语结构是elderly people consume or have，who引导定语从句修饰主语

I believe that the usage of the singular verb 'is' is correct since it refers to consumption. (A) is incorrect because it has a modifier issue. The opening modifier 'in up to 40 percent of elderly people' does not make sense with consumption or they. Consumption is not inside these people. Neither these people are inside the 40% of the elderly population.

与光同航
句意：调查显示，在富裕国家独立生活的老年人中，有多达40%的人对一种或多种必需营养素的消费不足，或者他们的血液中这些营养素的含量不足。
思路：1.in up to中的in不对，排除ABC
2.of后的elderly people living independently in affluent countries太长了，容易歧义，并且who不能紧接countries，排除D

Ron：B-- in fact, it's much worse than redundancy; it actually creates the nonsense meaning that people are somehow inside themselves while consuming nutrients.

they在语法结构上可以直接指surveys，和后面their形成矛盾，所以是指代歧义。本身A就有结构上的歧义。 如果or前后平行的是Surveys have....or they...这两个结构的话they就是指代surveys了，这个时候or前面要用逗号隔开；如果是in up to 40 percent...or they...平行的话，那么or前面需要加that；所以A在结构上的问题，直接造成了they的指代歧义。
