Answer:
B. Socrates began a school where he educated students like Plato, laying the foundations for his own branch of philosophy.
Step-by-step explanation:
Socrates was a Greek Philosopher who had existed between the period of 470 to 399 BCE. He taught various students among which was Plato, another Greek philosopher who also existed between 428 to 328 BCE.
However, Socrates didn't have his philosophical writings. He only taught his students verbally. It was Plato one of his students that was influenced by his Socratic irony and method that later put his school of thought into writing.
Hence, Socrates began a school where he educated students like Plato, laying the foundations for his own branch of philosophy.
