c. Internal political conflicts

Od. Harsh climate conditions

b. Smallpox epidemic

The correct answer is b. Smallpox epidemic.

To determine the factor that contributed to weakening the Aztecs further during the siege of Tenochtitlán, we can analyze historical information about this event. The siege of Tenochtitlán took place in 1521 when the Spanish conquistador Hernán Cortés and his army attacked the Aztec capital.

One of the factors that contributed to weakening the Aztecs further during the siege was a smallpox epidemic. Smallpox was a highly contagious and deadly disease brought by the Europeans to the Americas. The Aztecs had no prior exposure to this disease, which made them highly vulnerable. The smallpox epidemic severely affected the Aztec population, causing sickness, death, and further weakening their overall strength and ability to defend themselves.

To find this answer, you can refer to historical records, accounts of the siege written by both Spanish conquistadors and indigenous sources, or scholarly articles and books about the history of the Aztec Empire and the Spanish conquest of Mexico. It is important to consult reputable sources to gather accurate information about historical events.
