D Correct answer
Explanation

This is the correct option. All of the above factors influence the nature of soil. Plants affect soil development by supplying upper layers with organic matter, recycling nutrients from lower to upper layers, and helping to prevent erosion. Deep rooted plants contribute more to soil development than shallow rooted plants. Animals living in the soil also affect decomposition of waste materials.
