All of the strategies listed were associated with Jesuit missionaries in their efforts to evangelize Indigenous peoples in the Americas and elsewhere. However, if we are looking for a strategy most closely associated specifically with Jesuit missionaries, it would be "Jesuits created local, Indigenous communities called reductions to aid in conversion."
The practice of establishing reductions was particularly characteristic of the Jesuits in South America, where they formed semi-autonomous, organized communities for Indigenous peoples. This was part of their broader strategy to protect Indigenous peoples from exploitation and facilitate their conversion to Christianity.
Other strategies, such as advocating for Indigenous rights, learning local languages, and using educational institutions, were employed by various missionary groups, not exclusively by the Jesuits.
