Final answer:
Spanish colonizers used C) religious dialogue and understanding to create peace with the French, through Catholic missionaries who aimed to convert Native Americans to Christianity while practicing cultural accommodation.
Step-by-step explanation:
Spanish colonizers used their religion, Roman Catholicism, to create peace with the French by C) engaging in religious dialogue and understanding (option C) as a means of establishing mutual respect and cooperation.
Catholic missionaries went to great lengths to understand and connect with the native populations, helping bridge the gap between the two societies. They aimed to convert Native Americans to Christianity, but cultural accommodation was practiced, allowing them to retain their own way of life while becoming Catholics.
This approach fostered a sense of peace and tolerance, despite the otherwise tumultuous colonial period.
