The correct answer is D. The rhythm described is that of ventricular fibrillation, which is a feared complication of myocardial infarction that must be corrected immediately (CPR, defibrillation, IV and intracardiac drugs including epinephrine, lidocaine, or procainamide) if the patient is to survive.
In an accelerated idioventricular rhythm (choice A), a normal latent pacemaker in the ventricles depolarizes at a regular, accelerated rate of 50 to 100/min, each time producing unusually shaped (but similar to each other) QRS complexes. P waves related to the complexes are not seen.
In an accelerated junctional rhythm (choice B), the P waves are typically inverted and may precede, follow, or be hidden within regular QRS complexes that occur at a rate of 60 to 150/min.
In a premature ventricular contraction (choice C), an ectopic ventricular pacemaker inserts an ectopic beat (typically with a wide and bizarre QRS complex) before the next sinus beat occurs.
In ventricular tachycardia (choice E), wide and bizarre, but recognizable, QRS complexes occur at an accelerated rate.

Actually the scenario was to emphasize that VF is important in this case, I mean attending doctor must be aware of the fact but will try to do so.
