The correct answer is "B".

Latin America and Africa were seen as sourcing points for European Crowns. Immense mines that contained precious metals such as Gold and Silver were exploited by the Spaniards in the territories now known as Peru, Bolivia, and Mexico. Diamonds and other minerals were also being extracted by the French in Africa.
