Correct option is C
The correct answer is (c) It has lesser amount of humous but more of minerals generally harder and more compact.
Explanation:
● Soil is composed of distinct layers called horizons.
● B-horizon (Subsoil) contains less organic matter (humus) but is rich in minerals washed down from the topsoil.
● It is typically harder and denser than the A-horizon.
Information Booster:
● A-horizon (Topsoil) is rich in humus and is soft/porous.
● C-horizon consists of small lumps of rocks with cracks.
● R-horizon is the unweathered parent bedrock.
Additional Knowledge:
● Statement (a) – Describes the C-horizon.
● Statement (b) – Describes the A-horizon (Topsoil).
● Statement (d) – Describes the Bedrock layer (R-horizon.
