Alchen [17]

CPR is a cardiopulmonary resuscitation method of an emergency first aid tool used as a life-saving technique in case of heart attacks and drowning.

CPR is given to a person when the heart rate is very less and the pulse rate is very faint. The rate of the compression varies for age groups and should be given with a perfect rhythm and sync.

Cardiopulmonary resuscitation should be given as 30 compressions and then artificial breath or ventilation in between followed by another 30 compressions.

Therefore, option C. 100 compression in 1 minute is correct.
