Answer:
D) Folded mountain with jagged, rough edges
Step-by-step explanation:
The incident which happened some fifty million years ago was the collision of the Indian plates and the Eurasian plates thus giving rise to the folded mountains that are characteristic of the Himalayas. Subduction was not possible when these two plates collided because they had the same density.
So, the force with which the two plates collided resulted in the formation of folded mountains that rose upward. The peaks of these mountains were jagged, rough, and uneven.
