Solution

The correct option is A Humus
Humus is dark, organic material that forms in soil when plant and animal matter decays. It contains many useful nutrients for healthy soil, most importantly nitrogen. Thus humus makes soil more fertile. When humus is in soil, the soil will crumble. Air and water move easily through the loose soil, and oxygen can reach the roots of plants. Hence it supports more vegetation to grow.
