The correct option is C prompt heart to beat at normal rate
All of us have a natural pacemaker in our heart which produces electrical impulses that causes your heart to beat. Electrical impulses lay a route by which our cells communicate with one another. In case where our natural pacemaker is not fast enough or there is blockage in the way our cells communicate with eachother, this device called artifical pacemaker is installed. This device uses low-energy electrical pulses to cause or prompt the heart to beat at normal rate.
