Which of the following identifies a feature on the print by a datum identification symbol?

The selection of "Datum Feature" is accurate because a datum identification symbol is specifically used to denote a reference feature on a technical drawing. In GD&T, a datum is a theoretical plane, axis, or point that serves as a starting point for measurement or a reference for other features on the part.

When a datum feature is identified on a print, it is marked to clarify how other aspects of the part relate to it. This ensures that measurements and tolerances are applied consistently according to established references, allowing for precise manufacturing and inspection processes. A datum feature is critical in creating a reliable framework for defining the part's geometry and tolerancing.

The other terms, while relevant to part design and measurement, do not refer specifically to the identification of features via a datum symbol. "Feature of Size" relates to specific dimensions that are critical for ensuring fit and function, "Control Volume" pertains to a defined volume for analysis in engineering contexts, and "Inspection Area" outlines the regions on a part where quality checks may occur but does not relate directly to the designation of reference features.
