The Apartheid was the policy that was put into place in South Africa in 1948. This policy separated the all of the black Africans, Asians, and Europeans. The Apartheid was finally dismantled after numerous negotiations from 1990 to 1993.
The questions about language and religion depend a lot on where the 100 people are (assuming all of them are in the same place). In terms of money, 25 people would be really rich, 50 people would be middle income, and 25 people would be really poor( I'd probably be a middle income person). The specific amount of money would depend on the time period. Since there are only 100 people, at least 90% of them would have the same religion. Also, the chances of war and conflict are really low, because everyone would know each other.(Sorry my answer is so long)
I think the answer is B. I hope this helps! :)
