Consider the following features of soil.
(A) Colour
(B) Texture
(C) Thickness
(D) Amount of humus
(E) Permeability
Which of the above features are determined by parent rock.

Correct option is A

(A), (B) and (E).
The parent rock, or the original rock from which the soil is formed, has a significant influence on several soil properties, including:
 Color: The color of the soil is primarily determined by the minerals present in the parent rock. For instance, soils derived from iron-rich rocks tend to have a reddish hue, while those derived from limestone tend to be lighter in color.
 Texture: The texture of the soil, which refers to the relative size and distribution of soil particles, is also influenced by the parent rock. Coarse-grained rocks like granite tend to produce soils with a sandy texture, while fine-grained rocks like shale tend to produce soils with a clayey texture.
 Permeability: Permeability refers to the ability of soil to allow water to pass through it. This property is also influenced by the parent rock. Sandy soils, with larger pores, have higher permeability than clayey soils, with smaller pores.
