Pope Alexander VI Established the Line of Demarcation in Order

Pope Alexander VI established the Line of Demarcation in order to:

A) form closer ties between England and Spain, since those two countries would then control most of the Americas.
B) prevent European countries from colonizing the New World.
C) keep Spain and Portugal from openly fighting each other.
D) ensure that no other European nations settled in the colonies established by the English.
E) make certain that the Spanish were able to harvest as much gold and silver as they could.
