[求助]OG SC 1

establishing

1. OG SC 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
WHEN CHILDREN 这种表达对否？是否可理解为when they are children的省略。
反正TOEFL中WHEN CHILDRE是错误的，但在该题的解释中，ETS没提该点错误。

另ETS解释：Choice E includes an incorrect verb tense
(has occurred) and wrongly replaces when with as.
不是AS也有WHEN的意思，为什么用AS替换WHEN错呢？
