Situation B is advantageous to plants because A and B horizons are humus-rich regions and humus improves the texture of the soil, increases water holding capacity of soil and provides nutrients for the growth of plants.

Minerals are also present in A and B horizons. Humus and minerals make the soil fertile and help in the growth of plants. So growth and branching of roots in A and B – horizons is advantageous for absorption of water and minerals by plants.
