What ocean is on the East Coast of the United States?

The correct answer is the Atlantic Ocean, which is located on the East Coast of the United States. This ocean stretches from the Arctic Ocean in the north to the Southern Ocean in the south and serves as the eastern boundary of the U.S. mainland. The Atlantic Ocean is significant for many reasons, including its role in trade, navigation, and historical exploration.

While the Indian Ocean is located to the southwest of the Indian subcontinent and is not adjacent to the United States, and the Pacific Ocean is found on the West Coast of the country, the Southern Ocean is located primarily around Antarctica and also does not border the U.S. Therefore, the Atlantic Ocean is the only option that accurately represents the ocean that lies along the eastern shore of the United States, making it the correct choice.
