The correct answer is option 2, which states that the Suez Canal connects the Mediterranean Sea and the Red Sea. The Suez Canal is an artificial waterway located in Egypt that stretches across the Isthmus of Suez. It provides a direct route for ships traveling between Europe and Asia, bypassing the need to sail around the African continent. By connecting the Mediterranean Sea and the Red Sea, the Suez Canal allows ships to sail from the Atlantic Ocean to the Indian Ocean, saving time and distance. This has significant economic benefits by facilitating international trade and reducing shipping costs. It is important to note that options 1, 3, and 4 are incorrect as the Suez Canal does not connect these water bodies.
