The correct answer is D) the encouraged Greece to create a strong Navy

Explanation:

He constantly made a strong argument for the fortification of the Athenian Navy during his lifetime, and in 483 BC he managed to convince the Athenians to build a fleet of 200 triremes; these proved indispensable in the conflict with Persia.
