Which command allows you to create an arc in AutoCAD?

The command that allows you to create an arc in AutoCAD is "ARC." This command enables users to define an arc by specifying various parameters such as start point, second point, and endpoint, or by using different methods like defining the center point and radius or the angles that the arc spans.

Understanding how to use the ARC command is fundamental in AutoCAD, as arcs are essential elements in many designs, including drafting, architectural plans, and engineering drawings. The flexibility of the ARC command allows designers to create smooth, curved lines, which can be critical for accurate modeling and visual presentations.

The other options, while related to drawing commands, do not specifically designate the creation of an arc; thus, the ARC command is the standard tool for this specific function in AutoCAD.
