Which of the following best describes minerals?

Minerals are best described as inorganic compounds and elements that are essential for various bodily functions. They are found throughout the body and play critical roles in processes such as building bones, transmitting nerve impulses, and maintaining proper fluid balance. Unlike organic compounds, which contain carbon and are involved in biological processes, minerals do not contain carbon and are classified as inorganic.

The correct choice reflects the fundamental nature of minerals, which are essential for numerous physiological functions and contribute to overall health. This understanding underscores the importance of minerals in the diet, as they must be obtained from external sources since the body does not produce them. Other options describe substances that do not accurately represent minerals; for instance, vitamins are organic compounds, proteins play different roles related to muscle and recovery, and organic compounds necessary for growth do not include minerals.
