Solution

The correct option is A (a) – (i); (b) – (ii); (c) – (iii)
P-wave represents the contraction of the atria (atrial depolarization)
QRS-wave represents the contraction of the ventricles (ventricular depolarization)
T-wave represents the ventricles returning to their normal state from their contracted state (ventricular repolarization)
