Concept:Soil texture describes the proportion of sand, silt and clay particles present in a sample of soil.
Explanation:Soil texture is based on the relative amounts of the different mineral particles that make up the soil.
It does not describe the amount of water soil can hold, so option A is not correct.
It is also not the arrangement of soil particles, because that is called soil structure, so option B is not correct.
Option D is too broad because soil contains other materials besides mineral particles.
Therefore, soil texture refers to the properties of the soil, silt and clay in a given soil sample.
This matches option C.
Answer:C. properties of soil, silt and clay in a sample of soil.
