Which of the following best describes silt?

Silt is best described as fine soil that is often used for farming because of its unique properties. It is made up of very small particles, which allows it to hold water and nutrients effectively while still draining well. This balance makes silt-rich soils particularly fertile, leading to productive agricultural practices. Silt is not as coarse as sandy soil, which tends to drain quickly without retaining moisture. Unlike organic materials found in soil, which come from decomposed living organisms, silt does not originate from organic sources. Additionally, while silt can be found in various environments, it is not specifically a dense soil like those typically found in forests. The characteristics of silt make it a significant component in many soils used for a variety of crops, making option C the most accurate description.
