"The sultan (of Beder) is a little man, twenty years old, in the power of the nobles. Khorassanians [Central Asians] rule the country and serve in war. There is a Khorassanian Boyar [Central Asian prince]". That quote explains the answer. This doesn't describe oligarchy because where does it say where small groups people have control of a country so A is not true. Centralized rule would correlate to direct dictatorship so B is not correct. D is not correct because absolute monarchy is not a form of government back from the Delhi Sultanate. The Delhi Sultanate used the feudal system which correlates to feudal vassalage making C, the correct answer.
