Answer:
The correct answer is B) Murieron por las enfermedades que trajeron los españoles. (They died because of the diseases brought by the Spaniards)
Explanation:
After the arrival of the Europeans, the population of indigenous people from all over the Americas (including Tenochtitlan) started to decrease obstreperously. While factors such as violence, war, exploitation, and massacres contributed greatly to the depopulation of the American indigenous people, the main cause for the natives' deaths were the devastating chronic diseases that were brought by Europeans -such as smallpox, influenza, bubonic plague, cholera, and malaria-.
