Explanations:Rajasthan, a state in northwestern India, is known for its diverse geography, which includes deserts, lakes, and mountain ranges. One of the most significant geographical features of Rajasthan is the Aravali Hills, which are the oldest fold mountains in India. The Aravali Hills run through Rajasthan from the southwest to the northeast, dividing the state into two distinct regions: the desert region in the northwest and the fertile region in the southeast.
The Aravali Hills are not only a prominent geographical feature but also play a crucial role in the state's ecology and economy. They act as a natural barrier, influencing the climate and rainfall patterns in Rajasthan. The hills are also rich in minerals and have been a source of various resources for the local population.
It is important to note that while the Aravali Hills are a significant feature of Rajasthan, other major mountain ranges like the Himalayas and the Western Ghats are located in different parts of India. The Himalayas are situated in the northern part of India, primarily in states like Uttarakhand, Himachal Pradesh, and Jammu and Kashmir. The Western Ghats, on the other hand, are located in the western part of India, primarily in states like Maharashtra, Goa, Karnataka, and Kerala.
Therefore, when considering the geographical features of Rajasthan, the Aravali Hills are the correct answer. The other options, such as the Himalayas and the Western Ghats, are not located within the borders of Rajasthan, making them incorrect choices for this question.
