What naval advancement did Themistocles develop for the Athenians? Included towers on the ships that allowed archers a better line of sight.

Equipped battleships with underwater rams.

Built larger ships that could withstand attacks.

Small, fast ships.

Equipped battleships with underwater rams.

Explanation:

Themistocles was able to persuade the Athenians to build a whole fleet of battleships called triremes. Triremes were built with a bronze ram mounted on the front that was used to ram enemy ships below the waterline, causing them to sink. The new ships were powered by three rows of oarsmen on each side who together could reach speeds of about five miles an hour, a very good speed for a battle ship. The trireme became a major asset to the Athenians, allowing them to gain control by sea of much of the land around the Mediterranean and the Black Seas.
