Solution

The correct option is C A-horizon of soil contains maximum amount humus
The uppermost horizon is generally dark in colour as it is rich in humus and minerals. The humus makes the soil fertile and provides nutrients to growing plants. This layer is generally soft, porous and can retain more water.
It is called the topsoil or $A-horizon$ of the soil.
