I“the [aztec] messengers also said [to montezuma]: ‘their trappings and arms are all made of iron. they dress in iron and wear iron casques on their heads. their swords are iron; their bows are iron; their shields are iron; their spears are iron. their deer carry them on their backs wherever they wish to go. these deer, our lord, are as tall as the roof of a house.’” in this aztec account, the tall “deer” that carried the spaniards on their backs were a. dogs c. horses b. donkeys d. wagons

The correct answer is C) horses.

In this Aztec account, the tall “deer” that carried the Spaniards on their backs were horses.

To understand this, let's have in mind that there were no horses in the American continent. It was the Europeans who brought horses to America. That is why the Aztecs -in this case- have never seen a horse and they compare it to something similar they had seen before, a deer. Horses for the Spaniards represented an advantaged in the purposes of conquest because horses can carry a heavy load and were used in battle.
