The correct option is C X- Aztec, Y- Maya
Before the Europeans discovered America, three centres of civilisations existed there. They were known as the Maya, the Inca and the Aztec civilizations. During the fourteenth century, the Aztecs from Mexico conquered the Maya country and founded their capital city of Tenochtitlan. The Aztecs formed a military nation and ruled for over 200 years. They had garrisons who were set of troops to guard specific locations. Although the empire had an outward security and peace, people were ruthlessly oppressed and exploited.
