OG10-183,多谢指点

183. Archaeologists in Ireland believe that a recently discovered chalice, which dates from the eighth century, was probably buried to keep from being stolen by invaders.

(A)  to keep from

(B)  to keep it from

(C)  to avoid

(D)  in order that it would avoid

(E)   in order to keep from

OG答案是B，可C为什么不对(chalice was buried to avoid being stolen.)？多谢各位指点！

顶个先

这边VERB+DOING中的逻辑主语不是一个，人去avoid chalice被盗,而不是chalice自己avoid被盗
