The classification of floatable solids includes both organic and inorganic types. Floatable solids are those that can remain suspended on the surface of the liquid due to their physical properties, primarily their density relative to the liquid. Organic solids, such as oils, greases, and some types of biodegradable materials, often exhibit floatability because they are less dense than water.

Inorganic solids, while often denser than water, can also be floatable under certain conditions. For example, certain types of plastics, wood, and other materials can remain afloat, making them floatable solids as well.

The option discussing only organic solids or only inorganic solids limits the classification to a single type, which does not encompass the capability of both categories to float. Therefore, recognizing that both organic and inorganic materials can be floatable is crucial in understanding solid waste management in wastewater processes.
