The correct option is:
C) Socrates began a school where he educated students like Plato.
While the phrasing in this option is slightly misleading—as Socrates himself did not establish a formal school, he engaged in dialogue and philosophical inquiry in a way that greatly influenced Plato and his writings. Socrates' method of questioning and his ideas about ethics, knowledge, and the examined life laid the philosophical groundwork for Plato's works.
