Concept:Soil is classified into particle size grades, and silt has particles ranging from $0.02\,\text{mm}$ down to $0.002\,\text{mm}$.Explanation:Soil separates are grouped by their diameters.Sand particles are the largest, while clay particles are smaller than $0.002\,\text{mm}$.Silt particles fall between fine sand and clay, with a diameter from $0.02\,\text{mm}$ to $0.002\,\text{mm}$.Therefore, the soil with particle size $0.02$ to $0.002\,\text{mm}$ is silt.Answer:B. silt
