An oligarchy- by definition- means, “A small group of people having control of a country, group, or organization.” (Source for definition: “Google”)
The answers not supported by this definition are: B, C, and D, as B and C are citizen-contributed systems, and D is a monarchy/dictatorship.
This leaves us with answer “A” being the only plausible answer to fit our description.
