C Correct answer
Explanation

Laterite forms in tropical regions with high rainfall through intense leaching of silica and soluble minerals, leaving behind iron and aluminum oxides. The oxidation process gives laterite its characteristic red color. Hydration, carbonation, hydrolysis, and calcification contribute to soil formation but leaching+oxidation is most critical for laterite.
