Answer:
He described an ideal form of government in his writing.
Step-by-step explanation:
The Greek philosopher Aristotle was a pupil of Plato and like his teacher, he was also interested in observing and describing/ working on what constitutes an ideal government. This stemmed from the wrongful accusation and death of Socrates which led to Pluto and eventually Aristotle critiquing and even suspecting a democratic government.
He famously stated in his "Politics" that "man is by nature a political animal". Like his teacher Plato, he also developed his own ideas about what constitutes an ideal government and analyzed all forms of government.
Thus, the correct answer is the fourth option.
