Correct answer is A

The promise to Abraham is found in Genesis 12:1-3. God called Abram (later named Abraham) to leave his country, his people, and his father's household and go to the land God would show him. In return for his obedience, God made a covenant with Abraham. God promises that He will bless Abraham, make him a great nation, and make his name great. He says that all peoples on earth will be blessed through Abraham.
