Answer:
A. Cultural diversity.
Explanation:
Back in the day of exploration, people still weren't familiar with other nations, especially those in the Americas. Europeans in particular were curious about those people, as well as those lands and resources, which is why they traveled there in order to achieve a number of things.
They sent adventurers to explore new territories. They sent missionaries to spread their religion. They sent soldiers to seize the land for them. However, during all of this, they encountered so many different cultures and nations, which is one of the main focuses of those narratives that talked about these eras: getting to know a different culture and ways to deal with it.
