Ans. The correct option is option A.
The parasympathetic impulse is responsible for such type of tracing.
The parasympathetic impulse gets initiated by slow influx of Na+ ion resulting in the prepotential followed by the rapid influx of Ca2+ which leads to depolarisation and outflux of K+ resulting in repolarisation.
