Correct Answer is C
Explanation
A. This would show a regular rhythm with a consistent rate (60-100 bpm) and clear P waves before each QRS complex, which is not present in asystole.
B. This indicates a slow heart rate (below 60 bpm) but would still display P waves and QRS complexes; asystole shows no electrical activity.
C. This is the correct interpretation as it represents a flatline on the ECG, indicating no electrical activity in the heart.
D. This would show a rapid heart rate (above 100 bpm) with present P waves, which is not the case in asystole.
