The correct answer is D. Loamy soil is highly porous and well-drained.
Sandy soil is composed of mostly sand particles, which are large and round. This makes it very porous, but also very loose and unstable. Clay soil is composed of mostly clay particles, which are small and flat. This makes it very dense and compact, and also very poor at draining water. Black soil is a type of loamy soil that is rich in organic matter. It is very fertile, but it can be heavy and difficult to work with.
Loamy soil is a mixture of sand, silt, and clay particles. This makes it a good balance between the porosity of sandy soil and the density of clay soil. It is also well-drained, which makes it ideal for growing a variety of plants.
