The PR Segment reside within the time frame amid the QRS complex’s beginning and the P wave’s end. It is generally through the baseline. In normal situations, though, it might be reduced through less than 0.8 mm and anything larger than that is pathological.

The P wave is generally the initial wave when we move downwards in the TP segment. It signifies both atria’s electrical depolarization. When the SA node fires the wave begins. It also comprises impulse’s transmission by the three internodal paths, the atrial myocytes, the Bachmann bundle themselves.

The QT interval is the ECG complex’s section surrounding the QRS complex, the T wave and the ST segment from the starting of the Q towards the T wave’s end. It denotes all of the ventricular systole’s events, from the starting of ventricular depolarization towards the repolarization cycle’s end. The interval differs with sex, age, electrolyte abnormalities and heart rate. The QT interval must be shorter than 1/2 of the earlier R-R interval.

So, option, (a), (b) (d) and (e) are not correct.

Waves are known as the deflections from the baseline. And baseline is known as the line which is from one TP segment to the another one.

So, option is correct.
