You're asked to compare three things here: wealth, location, and democratization. Start by narrowing the choices down using what you know.
You're comparing North America to Africa. North America is roughly considered wealthier than Africa as a whole because most areas in Africa are still in poverty. That eliminates choices C and D.
Democratization is the presence of democracies in the government. The majority of North America is led by democracies. Also democracies give people the freedom in their economy allowed for greater wealth. That makes B your correct answer.
The correct answer is - bison.
The Native Americans that were living on the Great Plains were heavily engaged into hunting bison, and were heavily dependent for survival on the bison meat as a food source, and the fur as a material for making clothes. Unfortunately, this led over time to a significant decrease in the number of bison herds on the Great Plains.
