The expansion of the maya empire into the aztec region was not a factor in the fall of the aztec empire. Option B is correct.

Cortes, helped by the Aztecs' native rivals, mounted an offensive against Tenochtitlan and defeated Cuauhtemoc's resistance on August 13, 1521. In all, some 240,000 people were estimated to have died in the city's conquest, which culminated the Aztec civilization.

Factors that gave way to the Fall of the Aztec Empire may be:

*diseases;

*tactics,

*the sacrifices (ritual Aztec sacrifices);

*religion;
