Choose the correct answer from the options given below:
Mohr and Van Baren classified soil development into distinct stages based on the maturity and characteristics of the soil profile.
Understanding the progression helps in classifying soils. The correct order according to this classification is:
This sequence traces the evolution of soil from its basic origins to a mature or final condition.
