The vital capacity is defined as the maximum volume of air that can be moved in or out of the lungs during a single breath. It is the difference between the maximum amount of air that can be inhaled and the maximum amount of air that can be exhaled. Therefore, option B "is the maximum volume that can be moved in or out during a single breath" is the correct choice.
