c. S-T
d. Q-R-S

None of the above. ECG lead have nought to do with pressure, solely electrical conduction. the depolarization of ventricles however is the QRS complex. the P wave is the atrial depolarization. the P-Q interval is the conduction adjournment at the AV node, the T wave is the repolarization of the ventricles, and the S-T segment is the duration of ventricular depolarization, this segment also demonstrates tissue ischemia.
