I read the posts on the link you provide but i still don't understand why we need to use "IT"...some say without IT, its not clear what to keep from being stolen??? but i think logically its crystal clear that its "chalice" which is keep from being stolen.

Also as i picked Op C as my answer so i don't have any idea why this is an incorrect idiom. These things are horrifying for a Non-native speaker like me. As this is an official question i have to accept the importance of this question.

Experts please help!!!
