Hey there!

The answer is C, the respiratory system.

Think about how when you breathe in and our, you're taking in oxygen through your lungs and throat, and letting our carbon dioxide. Your respiratory system takes that oxygen you're given and is able to effectively transfer it to the blood so it can supply oxygenated blood to places like the brain, heart, and all other parts of the body.

Hope this helps!
