Which statement best describes inorganic substances?

The statement that inorganic substances are not and never were alive accurately reflects the distinction between inorganic and organic substances. Inorganic substances typically refer to compounds that do not contain carbon-hydrogen bonds and are generally considered to be derived from non-living matter. This is significant in the study of chemistry and biology as it helps classify the types of materials we encounter.

For example, minerals, metals, and water all fall into the inorganic category because they are not products of biological processes. Understanding this classification is essential in fields like esthetics, where the properties and compositions of various substances can impact treatments and outcomes.

The other statements do not accurately encompass the nature of inorganic substances. They may imply characteristics or properties that are either too broad or misrepresent the essence of inorganic compounds.
