The 3-2-1 principle is the key to properly locating a workpiece. This principle involves using three points of contact to establish a plane, two points to create a line, and one point to lock the location in place.

Option B is also important as datum refers to a fixed point of reference for measurements, but it is not specific to workpiece location. Option C and D are not specific principles for workpiece location.
