Answer:
Pacific Ocean
Explanation:
After the construction of the Panama Canal, the United States gained access to the Pacific Ocean. The Panama Canal connects the Atlantic Ocean (via the Caribbean Sea) to the Pacific Ocean, allowing ships to pass between the two oceans without having to travel around the southern tip of South America (Cape Horn). This strategic waterway significantly shortened the sea route between the east and west coasts of the Americas and facilitated global maritime trade and transportation.
