Which of the following pairs of "course – feature" is correct for the Himalayan rivers?

I. Upper course – Meander

II. Lower course – Ox bow lake

The correct answer is Option 4. 

Key Points

• In the Himalayan rivers, the lower course is indeed characterized by the formation of meanders.
• As the river reaches flatter terrain and the flow slows down, it begins to meander, forming bends and curves accentuated to such an extent that the inner ends of the loop come close enough to get disconnected from the main channel and exist as independent water bodies called as oxbow lakes.
• However, ox-bow lakes are not typically formed in the upper course of Himalayan rivers.

​Additional Information

• The Himalayan region is home to several major rivers that are crucial water sources for millions of people in South Asia.
• These rivers originate from the glaciers and snowfields of the Himalayas and play a vital role in the ecological and economic systems of the region.
