The correct answer is based on established guidelines for performing CPR on a child who is not breathing and has no pulse. In this scenario, the CPR cycle involves delivering 30 chest compressions followed by 2 rescue breaths. This sequence is based on the need to prioritize blood circulation and oxygenation effectively during a cardiac arrest.

Children often require a higher ratio of compressions to breaths to ensure sufficient blood flow to vital organs. The ratio of 30:2 is designed to maximize the effectiveness of chest compressions while also providing necessary rescue breaths to address the lack of oxygen in the body. This method helps to maintain a degree of circulation and deliver oxygen to critical tissues until advanced medical help arrives.

The other options either suggest an incorrect ratio or an inappropriate method for providing rescue breaths alongside chest compressions. In particular, any option that alters the established 30:2 ratio does not align with the recommended practices for CPR in child care, which could ultimately affect the outcome in a life-threatening situation.
