1. The Wallerstein study indicates that even after a
decade young men and women still experience some
of the effects of a divorce occurring when a child.
(A) occurring when a child
(B) occurring when children
(C) that occurred when a child
(D) that occurred when they were children  
(E) that has occurred as each was a child

对于解释中一句话我不能理解："Choice A incorrectly introduces the when... phrase with occurring, thus illogically making divorce the grammatical referent of when a child"
ving和that从句在reference上有什么区别吗？
谢谢~~~

它的意思是a divorce occurring when...会产生歧义.选D
