Soil is a mixture of a. solids b. solids, liquids, and gases c. solids and liquids d. solids and gases

The correct answer is option b. solid, liquids and gases.  

The soil is a mixture of three matters present in the nature. The basic constituent of the soil is solid particles. The solid particles of the soil come from the rocks or the minerals. This solid part of the rock is moist with the liquid (water), and air (gas) is also present mixed with the fine solid particles present in the rock.
