Answer: C. Converting indigenous peoples to Roman Catholicism was a major motivation for Spain, whereas Great Britain emphasized economic and political control.
Step-by-step explanation:
The Spanish were very interested in converting indigenous people to Catholicism in their colonies and to this end, established many missions where their priests could reach out to the local populations. They also intermarried with the local populations.
This was in contrast to the British. While they cared about converting the locals to Christianity, it was a very secondary motivation for them as the primary aim was to ensure economic and political control so that resources could be used for the benefit of Great Britain.
