Which of the following is the soil type most suitable for building homes?

Gravel is the most suitable soil type for building homes due to its excellent drainage properties and high load-bearing capacity. This type of soil has larger particles that allow water to pass through quickly, reducing the likelihood of water accumulation that can lead to foundation issues. Additionally, gravel compacts well and provides a stable base for structures, minimizing the risk of settling or shifting over time.

In contrast, fine sand, while it can also provide good drainage, lacks cohesion and may not support heavy structures as effectively as gravel. Organic soil contains decomposed plant material which can compress over time and is prone to moisture retention, making it less stable for foundations. Coarse sand has larger particles than fine sand but does not typically provide the same level of stability and drainage as gravel, making it less ideal for construction purposes.
