Which statement describes the composition of a tablet?

The correct choice accurately describes the composition of a tablet by highlighting that it consists not only of the primary medication but also includes additional substances such as binders and fillers. Binders are necessary for holding the ingredients together, helping to form the tablet's shape and integrity. Fillers serve to bulk up the tablet to a size that is easy to handle and swallow, and they can influence the tablet's dissolution and absorption characteristics. This combination is essential to ensure the tablet can be manufactured properly, remain stable, and deliver the medication effectively when ingested.

The other options do not capture the full essence of what a tablet is. A tablet does not contain solely the primary medication since it requires other components to maintain its structural integrity and functionality. It is not an alcohol-based solution, as tablets are solid dosage forms. Furthermore, tablets are not liquid medications; they are designed to be solid, which distinguishes them from other forms of medication delivery such as syrups or suspensions.
