[問題]SC885 sectionA-12

[uniqueben]

12.Darwin was not the first to advance a theory of evolution; his tremendous originality lay in the fact that he proposed the idea of natural selection as the means by which evolution worked.
(A) lay in the fact that he proposed the idea
(B) lay in the fact of his proposing the idea
(C) laid in the fact of his proposing the idea
(D) laid in his proposal
(E) lay in his proposal

請問一下，這裡的lay in his proposal是什麼意思啊？
選項A、B、C錯的原因是為什麼呢？(fact和propose應該不是redundancy吧？)

thanks~
