The correct answer is:
D

The part marked is Bundle of His.

The Bundle of His arises from the AV node and runs along the interventricular septum, carrying the impulse downwards to the Purkinje fibres. Its role is to carry the cardiac impulse from the AV node to the ventricles, ensuring coordinated ventricular contraction.
