The QRS complex should be positive in leads that are oriented towards the area of the heart where the depolarization wave is moving towards. The positive leads in the standard 12-lead ECG include leads I, II, III, aVR, aVL, aVF, V3, V4, V5, and V6. Therefore, the only option among the given choices that is a positive lead is C (V6). The other three options are either negative leads (AVR) or leads that are oriented towards the anatomical areas where the QRS complex is usually negative (V1 and V2).
