A) Carbon dioxide is inhaled into the lungs.
B) Oxygen comes out of the capillaries of the lungs.
C) Oxygen is picked up by red blood cells in the lungs.

Answer 1

the answer is C as the arrow for oxygen is towards the red blood cells indicating that red blood cells take in the oxygen

Answer 2

The correct answer is option C

The figure here represents that the oxygen is being taken up by the red blood cells in the lungs and will be transported to the whole body.

In return the carbon dioxide diffuse into the blood capillaries and is carried back to the lungs to get exchanged by oxygen.

This process of exchange of gas is called as respiration.
