The right answer is B. The Catholic Monarchs supported Columbus in his project to reach Asia, allowing him to make four trips (in 1492, 1493, 1498 and 1502). In the first one of them he arrived not to India (as he expected) but to the island of Guanahani, in the Bahamas. In addition, they granted him a certain number of privileges, such as the title of Admiral, Governor and Viceroy of the Indies, and a percentage of the riches he found.
