Answer 1

Hint: A mountain is an elevated part of the Earth’s surface with a steep slope and a conical shape. A series of mountains arranged in a line is known as a mountain range. A number of mountains ranges together form a mountain system.

Complete step by step solution:
Depending on how long ago they were formed, mountains can be classified as young and old mountains. Old mountains are much lower in height in comparison to young mountains as they get worn down by the forces of nature such as wind, water, and ice, over time. Old mountains have rounded peaks and gentle slopes.
In India Aravallis mountains range is the largest old mountain. Aravallis mountain is a type of fold mountain. It is situated in the Northwest part of India extending upto south west direction. Guru Shikhar is the highest peak in the Aravalli mountain range.

So the correct answer is (B).
