Answer: b) The Himalayas
Explanation: A collision between the Indo-Australian plate and the Eurosian plate led to the formation of the Himalayas. The present structure was formated by several steps, the first step was the collision of the Gondwana plate and Angara plate where the sea bed rose into longitudinal ridges and valleys, in the second collision step the Tethys bed rose greatly causing the final retreat of sea, forming the Great Himalayas and the Tibetan retreat of the sea. The third step was the formation of the lower Himalayas followed by the fourth step where the Himalayas ranges were elevated and the Sub Himalayas were raised. This last step led to the current structure of the Himalayas.
