The answer is: letter B, Despite geographical barriers, some African states were able to maintain diplomatic and cultural contacts with the broader Afro-Eurasian world.

Explanation:

As it was mentioned, three young ambassadors from the Kingdom of Ethiopia arrived at Naples (a city in Italy) in 1450. One of the ambassadors was an Italian man named Pietro Rombulo. He told His Highness about the situation in Ethiopia and how people there have been influenced by Christianity. He also honored the Ethiopian King because he was the most civil of all people and he was just.

Clearly, this means that although some African states have geographical barriers (like the Mediterranean Sea), they were able to have diplomatic relations with other African states and foreign people. They were also open enough to accept other cultures such as the religion of Christianity thus, explaining the prevalence of the religion in the area.
