Step 1: About Plato.
Plato was a classical Greek philosopher and student of Socrates, who later became the teacher of Aristotle. He founded the Academy in Athens — one of the earliest institutions of higher learning in the Western world.
Step 2: Life span of Plato.
Plato was born in 427 BC and died in 348 BC. These dates are historically well-documented and widely accepted by scholars.
Step 3: Analysis of options.
- (1) 384–322 BC: This corresponds to Aristotle, not Plato.

- (3) 427–348 BC: Correct, historically accurate lifespan of Plato.
- (4) 421–328 BC: Incorrect, not matching Plato’s known lifespan.
Step 4: Conclusion.
Thus, Plato lived from 427 BC to 348 BC.
