[2025-10-02T06:28:27.592110] [PI reasoning] **Determining CPR ratios**

I need to recall the standard guidelines for adult CPR, which say it's 30 compressions to 2 breaths, commonly noted as 30:2. Among the options, D seems to indicate this with "30:02:00", though it's a bit misformatted. Options C, B, and A suggest different ratios, like 30:1 or even 10:1, but D is the most accurate choice. I plan to cite the AHA guidelines for validation.
