Answer 1

Hint: The Himalayas, or Himalaya, is a mountain range in Asia isolating the fields of the Indian subcontinent from the Tibetan Plateau. The reach has huge numbers of Earth's most noteworthy pinnacles, including the most noteworthy, Mount Everest, at the line among Nepal and China.

Complete answer: The Aravalli Range, a dissolved stub of antiquated mountains, is the most established scope of overlap mountains in India.The regular history of the Aravalli Range goes back to times when the Indian Plate was isolated from the Eurasian Plate by a sea. The Proterozoic Aravalli-Delhi orogenic belt in northwest India is like the more youthful Himalayan-type orogenic belts of the Mesozoic-Cenozoic period (of the Phanerozoic) regarding segment parts and seems to have gone through a close methodical Wilson supercontinental pattern of occasions. The reach rose in a Precambrian occasion called the Aravalli-Delhi Orogen. The Aravalli Range is an upper east southwest moving orogenic belt that is situated in the northwestern piece of Indian Peninsula. It is essential for the Indian Shield that was framed from a progression of cratonic collisions. In antiquated occasions, Aravalli were incredibly high however since they have worn out totally by a long period of time of enduring, though the Himalayas being youthful crease mountains are still persistently rising. Aravalli, being the old crease mountains, have quit becoming higher because of the end of upward push brought about by the halting of development of the structural plates in the Earth's outside layer underneath them. The Aravalli Range joins two of the antiquated earth's outside portions that make up the more prominent Indian craton, the Aravalli Craton which is the Marwar section of earth's covering toward the northwest of the Aravalli Range, and the Bundelkhand Craton fragment of earth's hull toward the southeast of the Aravalli Range.

Thus, Option D is right.

Note: Cratons, by and large found in the insides of structural plates, are old and stable pieces of the mainland lithosphere that have remained moderately undeformed during the patterns of consolidating and breaking of landmasses.
