The most accurate reason from the options provided is "resistance to European diseases." The Spanish conquest of the Aztecs and Incas was significantly aided by the devastations of diseases such as smallpox, which decimated indigenous populations and weakened their societies, making them more vulnerable to conquest. While there were other factors involved, including military technology and alliances, the impact of European diseases was a critical element in the Spanish conquests.
