Which of the following describes a Doric column?

The Doric column is recognized as the oldest and simplest of the classical Greek architectural orders. This style is exemplified by its sturdy, fluted shaft with a simple, circular capital at the top and no base, resting directly on the stylobate (the upper step of a temple platform). The Doric order emphasizes strength and functionality, reflecting the utilitarian nature of the structures it adorned, such as temples dedicated to the gods.

Other options describe different architectural features or styles that do not align with the characteristics of Doric columns. For example, the mention of intricate designs and elaborate decorative features pertains more to the Corinthian and Ionic orders, which are known for their ornate capitals and bases. Additionally, the reference to baroque architecture highlights a different historical era and style, where dramatic elements and complexity were more prevalent, contrasting with the simplicity of Doric columns.
