So, to sump up, choice 1 and choice 2 are the correct options.

Answer:
the oxygen concentration decreases only when the air reaches the alveoli, which are the terminal branches of the respiratory system

The statement ''the oxygen concentration decreases only when the air reaches the alveoli, which are the terminal branches of the respiratory system'' explains the change in oxygen concentration of the inspired air
