Question

Explanation:

The Caribbean Sea is located to the north of South America. On the map, letter C is positioned in that area. The Gulf of Mexico is more to the northwest (near Mexico), Hudson Bay is in northern Canada (not shown in this South - America - focused map), and the Panama Canal is a man - made waterway (not a body of water like the options here).
