In a study of gas exchange, measurements were taken on four people. For all four people, the efficiency of gas exchange was identical. During normal breathing, which person, A, B, C or D, absorbed the greatest amount of oxygen? The figures are: A: breathing rate $14$ breaths per minute, tidal volume $0.6\,\text{dm}^3$, total lung volume $6.4\,\text{dm}^3$ B: breathing rate $15$ breaths per minute, tidal volume $0.6\,\text{dm}^3$, total lung volume $6.0\,\text{dm}^3$ C: breathing rate $16$ breaths per minute, tidal volume $0.5\,\text{dm}^3$, total lung volume $6.4\,\text{dm}^3$ D: breathing rate $17$ breaths per minute, tidal volume $0.5\,\text{dm}^3$, total lung volume $5.8\,\text{dm}^3$
