Answer
B.

C.
Both are 2-D
D.

Answer: Option A

Solution

Answer: Option A
Solution:
The soil profile is the vertical section of the soil from the ground surface downwards to where the soil meets the underlying rock. Whereas a pedon is a sample of a body of soil that is 1 m2 at the surface and extends to the bottom of the soil.
A soil profile is smaller than a pedon.
A soil profile is 2-D whereas a pedon is 3-D.
