The correct answer is option 1, The Philosophical School. The ancient school of law refers to the period in history where legal concepts were explored and studied from a philosophical standpoint. This approach aimed to establish a rational and logical understanding of law by examining its underlying principles and theories. Philosophers of the ancient school of law, such as Aristotle and Plato, analyzed the nature of justice, ethics, and the role of law in society. They sought universal principles that could guide legal systems and provide a basis for moral decision-making. The other options listed, Historical School, Analytical School, and Sociological School, represent different schools of legal thought that emerged in later periods, each with their own unique approach to understanding and interpreting law.
