Final answer:
Land management is not one of the five primary soil-forming factors, which are climate, organisms, relief, parent material, and time.
Step-by-step explanation:
The five primary soil-forming factors include climate, organisms (biological activity), relief (topography), parent material, and time. These factors contribute to the development and characteristics of soil profiles over time. Among the answer choices provided, land management is not one of the primary soil-forming factors as it is a human activity that can influence soil but is not considered in the natural formation and evolution of soil profiles.
