Answer 1

Correct Answer - Option 1 : Lake Baikal

The correct answer is Lake Baikal.

• Lake Baikal:
  • It is a rift lake in Russia, located in southern Siberia, between Irkutsk Oblast to the northwest and the Buryat Republic to the southeast.
  • Lake Baikal is the largest freshwater lake by volume in the world, containing roughly 20% of the world’s unfrozen surface freshwater. Hence, Option 1 is correct.
  • It contains more water than the North American Great Lakes combined.
  • It is the world’s deepest lake. 
  • It is considered among the world’s clearest lakes and is considered the world’s oldest lake — at 25 million years.
  • It is the seventh-largest lake in the world by surface area.
  • Lake Baikal was formed as an ancient rift valley, having the typical long crescent shape.
  • This lake was declared a UNESCO World Heritage Site in 1996.​

Superior Lake	The largest freshwater lake in the world was Lake Superior (by surface area). It is located on the border of the United States of America & Canada. It has a surface area of around 82,103 km sq. Cities on its bank: Marie, Thunder Bay, Duluth, Superior, Sault Ste, Marquette.
Lake Michigan–Huron	It is the body of water consisting of Lake Michigan and Lake Huron, which are joined through the 5-mile-wide, 20-fathom-deep, open-water Straits of Mackinac.
The Caspian Sea	It is the world’s largest inland body of water, variously classed as the world’s largest lake or a full-fledged sea. As an endorheic basin, it lies between Europe and Asia. An endorheic basin is a drainage basin that normally retains water and allows no outflow to other external bodies of water, such as rivers or oceans, but converges instead into lakes or swamps, permanent or seasonal that equilibrates through evaporation
