Final Answer:
Tenochtitlan was strategically chosen for its greatness due to Natural Defense. Positioned on an island in Lake Texcoco, it provided a natural barrier against potential invaders. While the area had rich agricultural land and access to freshwater, the primary factor was its formidable natural defense. So, the correct answer is C) Natural Defense.
Step-by-step explanation:
Natural Defense Priority: The primary reason for selecting Tenochtitlan's location was its natural defense. Being on an island in Lake Texcoco offered a strategic advantage against potential threats.
Rich Agricultural Land and Freshwater: While the region had fertile land and abundant freshwater, these factors were secondary to the crucial consideration of natural defense in the decision-making process.
Not Access to Trade Routes: While being on a lake facilitated trade, it wasn't the primary reason for the site's greatness. The emphasis was on the defensive advantages provided by the island location.
Therefore, the correct answer is C) Natural Defense.
