The correct answer is: C. Mountainous soil.
Forest soils are soils that are found in forests. They are typically deep, well-drained, and have a high organic matter content. Forest soils are important for the growth of trees and other plants, and they also play a role in the water cycle and the carbon cycle.
Mid hill soil, low hill soil, and dry hill soil are all types of soil that are found in hills. However, they are not considered to be forest soils. Mid hill soil is a type of soil that is found in the middle of a hill. It is typically a mix of sand, clay, and silt. Low hill soil is a type of soil that is found at the bottom of a hill. It is typically a mix of sand, clay, and silt. Dry hill soil is a type of soil that is found in a dry area. It is typically a mix of sand, clay, and silt.
Forest soils are important for the growth of trees and other plants. They are also important for the water cycle and the carbon cycle. The water cycle is the process by which water moves from the Earth’s surface to the atmosphere and back again. The carbon cycle is the process by which carbon moves from the Earth’s atmosphere to the Earth’s surface and back again.
