Guru Shikhar Peak is located in the Indian state of Rajasthan. It serves as the highest peak of the Aravalli Range with an elevation of around 1,722 meters above sea level. Hence, option 1 is correct.
Option 2, Gujarat, is incorrect. While Gujarat does have significant mountain ranges such as the Gir Range, the Guru Shikhar Peak is not located here.
Option 3 suggests Madhya Pradesh; however, this is also not accurate. Although Madhya Pradesh is known for its diverse topography with mountains, rivers, and plains, the Guru Shikhar Peak is not among them.
Lastly, option 4, Maharashtra, is incorrect too. While Maharashtra is home to the Western Ghats (also known as the Sahyadri mountain range), the Guru Shikhar is not a part of this landscape.
In conclusion, Guru Shikhar Peak can be found only in Rajasthan and not in any of the other states mentioned in the options.
