Which soil order under USDA Soil Taxonomy is characterised by a well-developed argillic (clay-accumulated) subsurface horizon, moderate to high base saturation, and is typically formed under forest vegetation in humid temperate to subtropical climates, corresponding broadly to some of the red and lateritic soils found in parts of peninsular India?

A Alfisols (with a clay-enriched B horizon and moderate to high base saturation)
B Entisols (very young soils with minimal horizon development)
C Aridisols (found in extremely dry climates)
D Histosols (organic soils formed in waterlogged conditions)
