United States
B.
Brazil
C.
South Korea
D.
Russia
E.

Correct answer is C. South Korea.

Explanation:

C is correct answer because according to data South Korea, together with North Korea is at the top of the list. In general East Asian countries are the most homogenous countries in the world.

All of other countries on the list are far from being homogenous. This especially goes for Chad and African countries in general, but also for Brazil. Still, it is interesting that United States are more homogenous than Brazil.

After Korea, Russia is the most homogenous on this list.
