Which combination would likely produce the greatest surface stability?

Vegetation helps hold soil in place with its roots, while a well-structured loam resists erosion better than loose or thin soil. Together, these features make “well-structured loam with vegetation” the most stable surface. Dry fine-textured soil may be easily eroded, and clay-rich soil on a slope can be prone to runoff or sliding.
