Quizplus · Accepted Answer

Loam is a soil type that consists of an almost equal mix of sand, silt, and clay, which makes it ideal for plant growth as it has good drainage, aeration and water retention capabilities. Humus refers to the organic portion of soil, Regolith refers to the layer of loose rock and soil covering the bedrock, and Solum refers to the upper layer of soil that contains organic matter and is affected by biological activity. None of these terms describe a mix of sand, silt, and clay. Therefore, option D) loam is the best choice.
