CPR is administered to someone who is not breathing and has no pulse.

Explanation:
When someone is not breathing and has no pulse, they are in cardiac arrest and CPR is started to restore circulation and oxygen delivery. Chest compressions push blood through the heart and to the brain and other vital organs, while rescue breaths provide oxygen to the bloodstream. This combination buys time until professional help arrives or an automated external defibrillator can be used. The other options don’t fit because CPR is not given if there’s a pulse, and being conscious isn’t the determining factor—the key is the absence of both breathing and a pulse.
