D Correct answer
Explanation

The question uses double-negative logic: it asks which statement about soil formation is NOT correct. Option D states that plant roots play no role, which is indeed false - plant roots actively contribute to soil formation by breaking up rocks and adding organic material through decomposition. The other options correctly describe soil formation processes.
