Answer: C
Correct answer: Shiwaliks, Lesser Himalaya, Greater Himalaya
The Himalaya run in three roughly parallel ranges, and from south to north they are the Shiwaliks, the Lesser Himalaya and the Greater Himalaya. The Shiwaliks, or Outer Himalaya, are the lowest at 900 to 1,100 metres, made of unconsolidated sediment eroded from the ranges behind and therefore prone to landslides. Between them and the range above lie the flat-floored valleys called duns, of which Dehradun is the best known. The Lesser or Middle Himalaya rise to 3,700 to 4,500 metres and contain the hill stations - Shimla, Mussoorie, Nainital, Darjeeling - along with the Pir Panjal, Dhauladhar and Mahabharat ranges and the Kashmir and Kangra valleys. The Greater Himalaya, or Himadri, is the highest and most continuous, averaging 6,000 metres and carrying Everest, Kangchenjunga and Nanda Devi, with perpetual snow and the sources of the great rivers. Beyond them lies the Trans-Himalaya, including the Karakoram and Ladakh ranges.
