Correct Answer: Option (C) — A is true but R is false
Concept & Option Breakdown
Standard Reference VerifiedAssertion (A) is true: West Bengal has a significantly higher percentage of net sown area (~60% of total geographical area) due to flat, fertile alluvial plains of the Ganga-Brahmaputra delta. In contrast, undivided Andhra Pradesh had a net sown area of around 40%.
Reason (R) is false: The predominant soil types in Andhra Pradesh are Red soils (covering the majority of the plateau) along with Black soils and Alluvial soils along coastal river deltas. Laterite soils cover only isolated, small patches on the Eastern Ghats and coastal uplands.
The dominant soil of the Deccan plateau/Andhra region is Red and Black soil, not laterite, making Reason (R) factually false.
