Answer

Brief Explanations:

The atrioventricular node is located in the interatrial septum and relays electrical excitation from the atria to the ventricles. The sinoatrial node is the heart's natural pacemaker and initiates the heartbeat, not a relay between atria and ventricles. There is no commonly - known "junctional node" in this context in the heart's conduction system as a standard term for this function.

Answer:

A. atrioventricular node
