Laterization is a process of accumulation in soil

Answer: Option A

Lateralization is the process of the accumulation of iron and aluminium oxides in the soil.
It is also termed tropical weathering and is a prolonged process of chemical weathering that produces a wide variety in the thickness, grade, chemistry, and ore mineralogy of the resulting soils.
Typical laterite is porous and claylike. It contains the iron oxides minerals goethite, HFeO₂; lepidocrocite, FeO(OH); and hematite, Fe₂O₃. It also contains titanium oxides and hydrated oxides of aluminum, the most common and abundant of which is gibbsite, Al₂O₃ · 3H₂O.
