Solution
The correct option is A Brings the air to body temperature During breathing, air is not brought to the body temperature. Diffusion of gases takes place between alveoli and capillary. Our nose hair cleans up the air. The mucous and the hair warm up the air but it is not up to the body's temperature.
Hence, the correct answer is 'Brings the air to body temperature'
