b.

d.
marathon

The correct option is A

The battle of Salamis was a naval combat that faced an alliance of Greek city-states with the fleet of the Persian empire in 480 a. C. in the Saronic Gulf, where the island of Salamis leaves two narrow channels that give access to the bay of Eleusis, near Athens. This confrontation was the high point of the Second Medical War, the second Persian attempt to invade Greece that had begun in 480 BC. C.

Xerxes had to retreat to Asia along with much of his army, but left his general Mardonio and his best troops to try to complete the conquest of Greece. However, the following year what remained of the Median army was defeated in the battle of Plataea and the Persian army in the battle of Mycala. After these setbacks the Persians did not return to try the conquest of the Hellenic world. The battles of Salamis and Platea marked a turning point in the course of the Medical Wars, since in the future the Greek polis took the initiative and went on the offensive.
