Which ECG feature represents active electrical contraction/relaxation with groups of waves?

Explanation:
A complex is the feature that represents active electrical contraction and relaxation with groups of waves. It’s a cluster of waves (for example, the Q, R, and S components) that together mark a single electrical event in the heart. The ventricular depolarization shown as the QRS complex drives contraction, followed by repolarization reflected in the T wave as relaxation. In contrast, a single wave is just one deflection, a segment is a flat stretch between waves, and an interval is a time span from one point to another. So, the term that best captures a grouped set of waves representing a coordinated electrical event is the complex.
