Correct Answer: Meghalaya
Subject: geography
Explanation: Saline soils (Usar/Reh) are predominantly found in Gujarat, Uttar Pradesh, and Bihar. Meghalaya is the odd one out. • Meghalaya, having extremely heavy rainfall (Mawsynram/Cherrapunji), primarily features heavily leached Laterite and forest soils. • Saline soils develop in areas of poor drainage and dry climates where salts (chlorides/calcium) accumulate on the top layer due to capillary action. • A, B, and C are the states correctly identified by agricultural data as having major saline soil tracts. • High Rain = Acidic/Laterite (Meghalaya). High Evaporation/Over-irrigation = Saline/Alkaline (UP/Gujarat). • Uttar Pradesh has the highest area under saline soil in India. • ट्रिक: उच्च वर्षा = लेटराइट/अम्लीय (मेघालय)। उच्च वाष्पीकरण = लवणीय/क्षारीय (UP/गुजरात)।
