What is the rate of oxygen consumption for a person at vigorous activity?

The rate of oxygen consumption for a person engaged in vigorous activity typically averages around 1.5 to 3.0 liters per minute, which translates to approximately 90 to 180 cubic inches per minute. This range is consistent with the higher physical demands placed on the body during intense exercise.

Given this understanding, the choice of 180 cubic inches per minute aligns closely with the expected consumption rates for vigorous activities, reflecting the body's increased need for oxygen while performing strenuous tasks. Factors such as the individual's fitness level, intensity of the exercise, and duration can influence this rate, but 180 cubic inches per minute is a commonly accepted figure for someone exerting themselves at high intensity, positioning it as the most accurate option among the given choices.

Other options either exceed the typical physiological limits for oxygen consumption during vigorous activity or fall below the expected range, thus making them less accurate in this context.
