The correct option is D Due to the collision between Indo-Australian plate and Eurasian plate resulting in the folding of the edges of the two plates
The Indian subcontinent was a part of Gondwana in the Southern Hemisphere. Due to the internal forces of the Earth, Gondwana broke further. The Indo-Australian plate separated from Gondwana and started drifting northwards. It collided with another plate known as the Eurasian plate. The collision resulted in the folding of the edges of the two plates and the Himalayas were thus formed.
