Answer 2

Answer:

C: Subsoil

Explanation:

The soil profile has layers which are referred to as horizons. The upper most layer of soil profile is A-horizon or top soil followed by B-horizon or sub soil. Top soil is the most fertile layer of soil due to presence of humus. Sub soil is comparatively harder, compact and lighter in color than the top soil. Horizon-C or bed rock follows the subsoil and is made of rocks and stones only. The last layer of soil profile is bed rock.
