Final answer:
The Layou River is neither the longest nor the deepest river in the world; the Nile River is the longest, while the Congo River is the deepest.
Step-by-step explanation:
The Layou River is not one of the longest and deepest rivers in the world. When studying the longest and deepest rivers globally, it's essential to consider those like the Nile River, which holds the title of the longest river, stretching over 4,000 miles through countries such as Uganda, Sudan, and Egypt. Another significant river is the Congo River, which is recognized as the deepest river system in the world, with some areas reaching depths of more than 700 feet.
