One legacy of Madison Avenue's recent campaign to appeal to people fifty years old and over is the realization that as a person ages. their concerns change as well.

  d中虽然their 和 people一致,但是concerns 前面能加单数...their肯定是错的...,而只能用 a person , his or her, concerns  这样前后才保持一致

(C) to realize that when a person ages, his or her
        

d\ to realize that when people age, their

楼上的错了。。。答案是B呀。。。

concerns跟在their后面做的名词，恰恰提示了用复数才对。
