Which of the following commands creates a circular array in AutoCAD?

The command that creates a circular array in AutoCAD is "CIRCULARARRAY." This command allows users to distribute objects evenly around a central point in a circular manner. When using the Circular Array feature, you can specify the center point, the number of items to be arrayed, and whether or not to define the angle between the items. This is particularly useful for designing objects like wheels, circular patterns, or any design that requires repeated elements in a radial arrangement.

The other options do not represent the correct command for creating a circular array. For instance, the "ARRAY" command provides various types of arrays, including rectangular and path arrays, but it does not specifically designate a circular arrangement. Therefore, the correct command for that specific function is "CIRCULARARRAY," which directly addresses the requirement of creating a circular pattern of objects in AutoCAD.
