C Correct answer
Explanation

Chemical weathering predominates in humid tropical regions because both high temperature and abundant moisture are required for chemical reactions to proceed rapidly. Warm temperatures accelerate reaction rates, while water is essential as a solvent and reactant. The tropics provide these conditions year-round, allowing for deep chemical weathering profiles (like laterites). Arid regions lack water, semi-arid has limited moisture, and Mediterranean regions have seasonal dry periods that slow chemical weathering.
