Answer: C. Battle of Marathon
Explanation:
The Battle of Marathon was fought in 490BC between Athens and Persia in what became known as the first invasion of the Greek mainland by the Persians and was led by Darius The Great.
Before the battle, the Athenians sent a message to request help from Sparta but the Spartans declined involvement due to their observance of a religious festival.
Regardless, Athens and her Allies inflicted a crushing defeat on the Persians that kept them out of Greece for over a decade before Xerxes the Great invaded their shores once more.
This therefore must be the battle that the text speaks of.
