B，時間狀語從句，修飾前面的the days.

答案的確為B,但when引導的不是時間狀語從句而是定語從句。when可以引導定語從句（有時可以用that代替；有時可以省略。）例如：Do you know the date when Lincoln was born? 你知道林肯的出生日期嗎？I glanced at my watch and realized that it was time (when) I left. 我瞅了一眼手表，才發覺是我該離開的時間了。There was a time when all scientists were willing to share their results. 曾經有一段時間，所有的科學家都愿意與人共享他們的成果。
