Solution
The correct option is C Purkinje fibre
The waves of cardiac muscle contraction originate from the sino atrial node or SA-node which is located in the right atrial wall and reach the AV-node which is situated at the base of the right auricle. The excitatory impulses from the AV node are rapidly transmitted to the bundle of His which lies in the interauricular and interventricular septum. From the bundle of His, it spreads throughout the walls of the ventricles via the Purkinje fibres.
