The Correct Option is A
Approach Solution - 1
In the Munsell colour system, the value component refers to the lightness or darkness of a color. A lower value, especially '0', indicates very dark color, which usually corresponds to high organic matter in soil, such as in humus-rich topsoil.

Approach Solution -2
Understanding the Munsell scale: Munsell colour notation has three components - hue (the colour itself), value (lightness/darkness), and chroma (colour purity).
The value scale runs from 0 (pure black) to 10 (pure white), so a value of 0 represents the darkest possible soil colour.
Dark soil colour is strongly associated with a high concentration of humified organic matter, which absorbs light and masks the underlying mineral colour, so a Munsell value of 0 indicates a high level of organic matter.
