Question

Please select the word from the list that best fits the definition form of government used by the Spartans

Answer 1

The answer is oligarchy, got it right.

Answer 2

The best way to describe Spartan government would be through a dual kinship - Namely, Spartan society was always ruled (when it was a city-state) by two kings where each of the two had their own opinion and say in the matters of the city.

While you didn't provide a list - it is true that dual kinship is the best definition for the type of government in Sparta.
