Which two philosophers significantly contributed to the field of political science?

The correct answer is that Aristotle and Plato significantly contributed to the field of political science due to their foundational work in political philosophy that has influenced countless theorists and governments throughout history.

Plato's contributions began with his idealistic thoughts on governance and justice, particularly in works like "The Republic," where he outlines his vision of a just state led by philosopher-kings. Plato introduced the concept of an ideal society and emphasized the importance of virtue and moral education in governance.

Aristotle, a student of Plato, further advanced political thought by using empirical observation and analysis in his work "Politics." He critiqued Plato's ideas and laid the groundwork for a more systematic and pragmatic approach to studying political systems and governance. Aristotle distinguished between various forms of government, analyzing their strengths and weaknesses, and he is often considered the father of political science for his methodical approach to the study of politics.

While the other choices mention influential philosophers, they do not share the same direct and foundational impact on political science as Plato and Aristotle.
