Model Answer

(B) Diffusion of iron in crystalline and metamorphic rocks

Explanation

The textbook explicitly states: "These soils develop a reddish colour due to diffusion of iron in crystalline and metamorphic rocks." Option C (leaching) is the cause of laterite soil formation, not red soil — a common confusion to avoid.
