Correct Answer: Option D — Forest and Mountain Soil. Forest and Mountain Soil is correctly identified as terraced and valley areas may support tea, spices and temperate fruits. Forest and Mountain Soil is also associated with a variable soil group formed under mountain vegetation and relief. Another identifying fact about Forest and Mountain Soil is that texture and humus content change markedly with altitude and slope. A further exam-relevant fact about Forest and Mountain Soil is that terraced and valley areas may support tea, spices and temperate fruits. Why the other options are incorrect: • Option A — Saline and Alkaline Soil: Saline and Alkaline Soil is drainage, leaching and gypsum treatment can aid reclamation where appropriate. It is incorrect here because Saline and Alkaline Soil is instead associated with a soil containing excessive soluble salts or exchangeable sodium. • Option B — Peaty and Marshy Soil: Peaty and Marshy Soil is prolonged saturation slows decomposition of plant material. It is incorrect here because Peaty and Marshy Soil is instead associated with an organic-rich soil formed in waterlogged conditions. • Option C — Khadar: Khadar is it is more frequently flooded than the older alluvial terraces. It is incorrect here because Khadar is instead associated with the newer alluvium of active floodplains. Exam Takeaway: Connect Forest and Mountain Soil with “terraced and valley areas may support tea, spices and temperate fruits” and “a variable soil group formed under mountain vegetation and relief” for revision.
