The correct answer is D) Hernán Cortés.
Hernán Cortés was a Spanish conquistador who led an expedition that caused the fall of the Aztec Empire and brought large parts of mainland Mexico under the rule of the King of Castile in the early 16th century. Vasco da Gama reached India by sea, Bartholomew Diaz was the first European to round the southern tip of Africa, and Ferdinand Magellan led the first circumnavigation of the Earth.
Cortés arrived in Mexico in 1519 and, through a combination of military force, strategy, and alliances with local indigenous groups hostile to the Aztecs, defeated the Aztec Emperor Moctezuma II and eventually conquered the capital Tenochtitlan in 1521.
