Answer:
The answer is A.The Greeks united to eventually beat the Persians.
However, the defeat suffered did not force the Persians to lay down their weapons immediately and forgo further operations. The Persian command continued to count on the help of its supporters in Athens.
Explanation:
After departing from the Marathon, the Persian fleet headed straight for Athens. The Athenian commanders discovered the plan of the Persians, and the Athenian army immediately went back and arrived at Athens in an accelerated march before supporters of the Persians could realize their plans.
Thus, when the fleet approached the port of Athens it was already under safe protection. The Persians stood at home for a while, and then sailed back to Asia.
At the Marathon, the advantages of the Athenian civilian army over the army of the Persian invaders were most clearly demonstrated.
