Which of the following factors was the most important in determining a person's social standing in spain's american colonies?

a. the person's opinion on the spanish caste system
b. the religion the person chose to worship
c. the length of time a person had lived in the americas
d. the races of each of the person's parents

I choose letter D. The races of each of the person's parents. Ancestry was the biggest factor in determining one’s social status in a Spanish colony.  Those who are pure Spanish that were born in Spain were the ones at the top.  The lesser your Spanish heritage the lower your standing in society.

c) legal battles last five weeks after the election due to the narrow victory in several states.
