Solution

The correct option is A Heart rate below 60 bpm
The rhythmic contraction and relaxation of the heart is called heart beat. Each heart beat includes one systole (contraction) and one diastole (relaxation). The heart of healthy person beats 72 times per minute. This is called heart rate. Bradycardia means slow heart rate usually below 60 beats per minute.
Thus option B is the correct answer.
