I think you would find it easier to decide if you would look at all of them in fractions. If you take the breathing rate and divide it by the oxygen content in the blood (or vice versa) you will find the extremes as both end of the 4 samples. The worst is person A and the best person C (least number of breaths to obtain the oxygen content in their blood). You don't really need to calculate though. The person C has a lower breathing rate than D but a higher oxygen content in their blood. I don't think an athlete at rest takes more breaths than a normal person.

A smoker would have a harder time getting O2 into their body, so they would have to breathe more and they'd have less O2 in their blood. An athlete would have a higher O2 to breath ratio.

  • A is the smoker
  • C is the athlete
