Which of the following best describes pills?

The correct choice defines pills as compressed powdered material that is formed into small, solid doses suitable for oral consumption. Pills are typically created by compressing a mixture of active ingredients and excipients into a tablet form, which can be conveniently swallowed. This process allows for a precise dosage of the active compounds, making it a popular method for delivering medicinal substances.

While semi-solid preparations or solutions involving alcohol may be used in herbalism or other forms of medicine, these do not accurately describe the conventional form of pills. The focus on compressed powdered materials underscores the prevalent method of making pills, which emphasizes their solid and compact nature tailored for easy ingestion and precise dosing.
