Multifocal PVCs are

Explanation:
Multifocal PVCs come from more than one ventricular focus, so the premature beats have different shapes on the same ECG strip. If you see PVCs with varying morphologies within a single tracing, that indicates multiple ectopic sites firing. In contrast, PVCs that all look the same across the strip come from one focus (unifocal/monomorphic). The other descriptions don’t define multifocality on their own, since different leads or inverted T waves can occur with various PVC patterns but don’t indicate multiple foci.
