Correct answer
Explanation
Lake Baikal in southern Siberia, Russia, is the world's deepest lake at approximately 1,642 meters (5,387 feet). It is also the world's oldest lake (25 million years) and holds about 20% of Earth's unfrozen freshwater. Lake Superior and Michigan are Great Lakes in North America; the Caspian Sea is the largest inland water body but not as deep as Baikal.
