Correct option is (a) Area of the vessel

The explanation is: The oxygen-balance technique involves the measurement of the parameters such as the temperature of gases at inlet and outlet, volume of broth in the vessel, air flow rate at inlet and outlet, mole fraction of oxygen at the inlet and outlet, the pressure at the fermenter inlet and outlet.
