Your answer: —  Â·  Correct: D
Explanation

The Himalayan vegetation exhibits distinct altitudinal zonation. Deodar (Cedrus deodara) is a highly valued endemic species primarily found in the north-western Himalayas, specifically within the altitude range of 1500 to 2500 metres [2]. Some sources further refine this temperate zone distribution, placing it between 1800 and 2600 metres [1]. In contrast, Chir Pine (Pinus roxburghii) typically occurs at lower elevations, generally between 900 and 1800 metres [2]. Saal (Shorea robusta) is characteristic of the sub-montane or tropical foothills, usually found below 1000 metres [3]. Spruce (Picea smithiana) generally occupies higher reaches above the Deodar zone, often predominating between 2300 and 3200 metres [3]. Therefore, Deodar is the species most accurately associated with the 1800 to 2600 metres range.
