Solution

The correct option is D Covering of soil with organic matter to help in moisture retention
Mulching is a method of soil conservation wherein organic matter is used to cover the soil and help the soil retain moisture. This forms a layer between the soil and the atmosphere to reduce evaporation. Over time, the mulch decays and becomes part of the soil, increasing its fertility and organic content.
