Answer:
The good answer is A.
Step-by-step explanation:
Some one hundred years before the arrival of the Spanish, an Aztec ruler called Itzcoatl launched a campaign to conquer more land and expand Aztec power in the valley of Mexico. They had the divine guidance of the Sun God, Huitzilopochtli, as they were his chosen people, according to Aztec historians. In 1426 AD Iztcoalt and his armies attacked and crushed the Tepanecs in a great battle. Other rulers followed a ruthless campaign of conquests to fulfill the glorious destiny of the Aztecs, the sons of the Sun God, who were the masters of the valley of Mexico.
