Given below are two statements
Statement I: Chemical weathering involves disintegration and decomposition of minerals
Statement II: Biological weathering accelerates physical and chemical weathering
Choose the correct answer:

Correct option is D

Statement I is incorrect: Chemical weathering mainly involves decomposition (not disintegration) of minerals through reactions like hydrolysis, oxidation, etc.
Statement II is correct: Biological weathering, through roots, microbes, and organisms, can enhance both physical and chemical weathering, making the process more effective.
