The correct answer is option 4, the Suez canal. The Suez canal is one of the busiest Oceanic trade routes in the world. It is a man-made waterway located in Egypt that connects the Mediterranean Sea to the Red Sea. The Suez canal provides a shortcut for ships traveling between Europe and Asia, reducing the travel distance and time significantly. This makes it a preferred route for shipping companies and traders transporting goods between these two continents. The canal is crucial for international trade, as it allows for easier access to the Indian Ocean and the Asian markets. Ships from various countries pass through the Suez canal every day, making it a bustling hub for global trade.
