To which of the following, a bundle of His passes stimulus of contraction?

The conduction pathway in the human heart; SAN→AVN→AV bundle→Bundle of His→Purkinje fibresA bundle of nodal fibres, atrioventricular bundle (AV bundle) continues from the AVN which passes through the atrio- ventricular septa to emerge on the top of the interventricular septum and immediately divides into a right and left bundle.These branches give rise to minute fibres throughout the ventricular musculature of the respective sides and are called purkinje fibres.
