Verified by Experts

The correct answer is:

The action potential starts at the sino-atrial node and passes to the atrioventricular node . From the atrioventricular node, the action potential enters the atrioventricular bundle (E) and disperses via the right and left branches of the AV bundle , and finally to the Purkinje fibers , ensuring coordinated ventricular contraction.
