The correct answer is D. Oligarchic
Step-by-step explanation:
In politics, the oligarchy is a type of government in which power is held by a small group of people that are different from others based on education, ethnicity, religion, etc. This implies decisions are taken by only a small group of the population and due to this oligarchies are often tyrannical and oppressive. This type of government was the one in South Africa from 1948 to 1994, because the country was controlled by a small group (around 18% of the population) based on ethnicity as those who held the power were white South Africans, also, due to this, the government was oppressive as certain rights such as voting in elections were restricted.
