D. Happened quickly

The compression that caused the Himalayan Mountains to form happened slowly and deformed a large area.

Explanation:

The Himalayan Mountains are the tallest mountains in the world, but also among the most massive ones when it comes to the area they occupy. These mountains are considered as young mountains, as they are still growing and the process will not end in the near future. The plates that have collided to form these mountains are the Eurasian and Indo-Australian ones, with the Indo-Australian plate dividing later and now it is a collision between the Eurasian and Indian plates.

The process of forming the Himalayas was slow. It took tens of millions of years and as mentioned it is an ongoing process. With two continental plates colliding, a very large area along the plate boundary experienced deformation, where the crust over a vast area was and still is lifted up, thus gradually creating the Himalayas. These mountains are so big and located in a place where they have managed to act as barriers between civilizations of several different regions in Asia.
