Which is a precept of the berit or Abraham's Covenant?

The choices can be found elsewhere and as follows:

A-Peace and harmony in society are achieved by strict adherence to Gods chosen leaders.

B-This sacred agreement with God defends Jews and marks them as the Chosen People.

C-Individual prayer and meditation are required to receive Gods love and blessings.

D-Complete obedience to the Jewish religious hierarchy is necessary to qualify for salvation

I believe the correct answer is option B. This sacred agreement with God defends Jews and marks them as the Chosen People. Hope this answers the question. Have a nice day.
