C. Predicted eclipses and developed a 365-day calendar.

Aztecs had two calendars, one was Xiuhpohualli, of 365 days, the other was Tonalpohualli, of 260 days. Astronomy was very well developed in the Aztec society, most priests studied the movements of celestial bodies to the point of getting a very accurate prediction of lunar and solar eclipses.

Huitzilopochtli was the Aztec god of war and it was linked to the sun. It was a tradition to make human sacrifices every 52 years in order to give him strength in his daily battle against the forces of the darkness, so the sun could shine again for the following 52 years.
