Option 2:
8%
Option 3:

Option 4: 16%
Correct Answer:
Solution : The correct option is 4.0%.
The carbon dioxide percentage of the air we breath is around 4.4%. This is approximately 100 times greater than the quantity of carbon dioxide in the air we breathe. Carbon dioxide in our exhaled breath is produced by the breakdown of food in our cells. We take in oxygen as we breathe in, which our cells require to break down food. This process produces carbon dioxide, which we exhale.
