a) They sent a runner to Athens to tell them of the victory and he said, "Victory is ours!" and then died of exhaustion is your answer.
The Battle of Marathon was well known, because while Athens was able to beat the much stronger Persian army, it was also where the term "marathon", and the event that "marathon" is used to describe was born.
The runner that they sent ran non-stop (typical of a marathon) from the battle field to Athens to deliver the news of victory. However, after getting there & delivering the news, he died, possibly from exhaustion.
