Which of the following mountain ranges in India is known as a young fold mountain range?

The Himalayas are among the youngest mountain ranges on the planet and consist mostly of uplifted sedimentary and metamorphic rock. They stretch from the Indus river in the West to the Brahmaputra river in the East. According to the modern theory of plate tectonics, their formation is a result of a continental collision or progeny along the convergent boundary between the Indo-Australian Plate and the Eurasian Plate. This is referred to as a fold mountain.
