Solution

The correct option is B AV node
B. AV node
Reason: The SA node (sinoatrial node) generates the impulse for the heartbeat. This impulse is then conducted to the atrioventricular node. The path followed by the impulse is from the SA node to the AV node to Bundle of His to the Purkinje system.
