b. Vindhyas
c. Western ghat
d. Aravallis

Answer 1

Hint: The peninsular plateau is a highly enclosed ancient plateau. Here are the remains of ancient ranges and evidence of glaciation is also found.

Complete solution:
The Aravali Range is the oldest mountain range in India, running from Rajasthan to Haryana. The Aravalli Range has eroded a series of ancient folding mountains. The Aravalli range is one of the most popular mountain ranges in India, also known as the Mewat hills.

While there are examples of horizontal movements in the Himalayas, there are many examples of 'vertical circulation' in the peninsular plateau. The 'Aravalli Range' is a highly ancient and residual range formed from rocks of the pre-Cambrian period.

It stretches from Gujarat to Delhi as a series of isolated hills. Its width varies from south-west to north-east and decreases gradually. The maximum height of Aravali is found in the 'Guru Shikhar' (1722 m) of Mount Abu. 'Vidhyachal' is a very old and surrounded folded mountain range. It is situated to the south of the Malwa plateau and separates northern India from southern India. Its average elevation is 700 to 1200 meters. It is about 1050 km from west to east in the form of Bharner, Kaimur, and Parasnath hills to Jharkhand. Is detailed in length. The 'Satpura' block is an example of a mountain, on either side of which are the famous geomorphic valleys of Narmada and Tapti.

This mountain range is situated to the south of the Vidhyachal and almost parallel to it and starts from the Rajpippala hills in the west and extends to the western boundary of the Chotanagpur plateau in the form of Mahadev and Maikal hills. Meets 'Dhupgarh' (1350 m) near the city. The highest peak of Maikal hill is 'Amarkantak' (1036 m). The Sone and Narmada rivers originate from here. Chotanagpur and Rajmahal hills are also part of the southern peninsula, after going east from Maikal. Ranchi's 'plateau' in Chotanagpur is a beautiful example of Peneplain.

Hence, the correct answer is option d.

Note:
The Chotanagpur plateau is also called the 'Roor of India', because it is the richest state in India in terms of mineral deposits. The Shillong Plateau (Meghalaya Plateau) is an immigrant of the Chotanagpur Plateau. The highest elevation of Satpura is the Panchmarhi of Mahadev hill.
