Final answer:
Recruiting native allies was crucial for the Spanish during their conquest of the Aztec Empire, as it helped them gain military support and valuable information, which is why the answer is true.
Step-by-step explanation:
The answer to the question is a. True. Recruiting native allies was indeed a critical strategy in the Spanish conquest of the Aztec. When the Spanish conquistadors, led by Hernán Cortés, arrived in the Americas, they were significantly outnumbered by the indigenous populations. By forging alliances with various native groups who were enemies of the Aztecs or had grievances against them, the Spanish were able to amass support and gather crucial information about the region. This strategy of using native allies not only helped in military confrontations but also assisted in undermining the political and social fabric of the Aztec Empire, leading to its eventual collapse.
