Answer:
The caste system is structured in terms of the businesses. The area of work defines what caste a certain person belongs to. Work lines such as agriculture and trade are considered as the higher and more prestigious castes whereas the lower level works such as music is considered as a caste of lower rank.
People are known from the caste background they belong to and that defines their role in the society. People tend to marry in the same caste to avoid mixing up in lower castes. some castes are given preference over other in the employment market. This also gives rise to inequality in the society.
I think the answer to this is B.
A) this could've been the correct answer because they are being run by a dictator of a president and they don't have enough government power to impeach him.
C) Like i said in A, they have a dictator as a president so there is no way C is the correct answer.
D) North Korea doesn't really have enough businesses they mostly do military stuff because of the stuff going around in the world.
C is the correct answer because they have a president who is spending their money on missile tests, building more weapons and all that bad stuff.
