#43. Although she had signed a pledge of abstinence [u]while being an adolescent[/u], Frances Willard was 35 years old before she chose to become a temperance activist.
(A) while being an adelescent
(B) while in adolescence
(C) at the time of her being adolescent
(D) as being in adolescence
(E) as an adolescent
Explanation says (E) is a correct answer, not (B) because [i]While in adolescence[/i] is not the correct idiom for this sentence.
If I think "she was" was omitted after "While", isn't (B) also correct? Why isn't it the correct idiom? Is this an idiom?
