Correct Answer
Option A
Detailed Explanation
The sino-atrial node initiates the electrical activity that leads to the depolarisation of the atria (P-wave), the QRS complex represents ventricular depolarisation, the pulmonary circulation involves the return of oxygenated blood to the left atrium, and the T-wave represents the repolarisation of the ventricles.
