Which of the following best describes 'Gravel, sand, loamy sand'?

The correct classification for 'Gravel, sand, loamy sand' is Type C soil. This designation stems from the Soil Classification System utilized in engineering, particularly when evaluating the characteristics of soil for construction and environmental purposes.

Type C soil is classified as having a low shear strength and is generally considered to be cohesive soil types that can support structures but may have variable properties. Gravel, sand, and loamy sand fall into this category primarily due to their particle composition and size. These soils typically have larger particles and are more granular, which makes them less cohesive than finer soils but still capable of sufficient stability under certain conditions.

The classification structure places Type A at the top tier, representing strong, cohesive soils like clay, while Type D includes highly compressible soils such as organic silts and clays, which present significant challenges for construction and stability. Type B is somewhat in between, representing soils with moderate shear strength. Therefore, gravel, sand, and loamy sand's particular characteristics fit squarely within the Type C classification.
