while being an adolescent, Frances Willard was 35 years old before she chose to become a temperance activist.
(A) while being an adolescent
(B) while in adolescence
(C) at the time of her being adolescent
(D) as being in adolescence
(E) as an adolescent
對於B選項為什麼不行我很疑惑,OG只有寫
While in adoleescence is not the correct idiom for this sentence.

我看了CD上有人寫說B不行是因為while指一小段時間, as才有一長段時間的意思? 真的是因為這樣嗎? 我想確定一下, 謝謝!
