B Correct answer
Explanation

Soil erosion is the removal of the top fertile layer of soil by natural forces like water and wind. This process is different from water absorption (option A) or adding fertilizers (option C), and results in infertility rather than being infertility itself (option D). The top layer contains most nutrients and organic matter, making its loss particularly damaging to agricultural land.
