Show answer & explanation
Correct answer: C
Concept
A soil group is the product of two controls - the parent material it develops on and the climate that weathers it. Because both vary systematically across India, every major soil group is diagnostic of a particular physiographic and climatic belt rather than of an administrative boundary. Matching a soil to a region therefore means asking, for each soil, which formative setting could have produced it.
Application
Read each soil in List-I for the formative control it implies, then locate the one region in List-II that supplies that control.
Soil type (List-I) | Formative control | Region it identifies (List-II) |
|---|---|---|
Alluvial soil (A) | Fine silt laid down repeatedly by large rivers across a flood plain | Indo-Gangetic plain, Bihar (III) |
Desert soil (B) | Very low rainfall with high evaporation over sandy, often saline parent material | Rann of Kutch, Gujarat (II) |
Black soil (C) | Weathering of Deccan basalt into a clayey, moisture-retentive regur | Krishna Tungabhadra basin (IV) |
Laterite soil (D) | Heavy monsoon rainfall leaching silica away and leaving iron and aluminium oxides behind | Western Ghats, Kerala (I) |
Cross-check
Each soil is used once and each region is used once, so the mapping must be one-to-one: A-III, B-II, C-IV, D-I. Two discriminators settle the pairs that are most often swapped. Black soil is tied to basalt, so it belongs to the Deccan tract drained by the Krishna and the Tungabhadra and not to the Ganga plain, whose cover is river-borne alluvium. Laterite needs intense leaching under heavy rainfall, which the windward Western Ghats supply and an arid Kutch landscape cannot.
A note on the source paper: its printed List-II described this entry as the 'Krishna Tungabhadra basin of Tamil Nadu', whereas the basin actually lies on the Deccan plateau across Karnataka, Telangana and Andhra Pradesh, so the region is named accurately here. The intended matching is unchanged.
Correct matching: A-III, B-II, C-IV, D-I.
