Anytime any element or molecule works in the body, the only way it is able to act is via it's polarity and solubility. In the case of Oxygen and Carbon Dioxide, they are both quite polar, and are very soluble.

So your answer is A
Numenius

Answer: (A) They are non polar and soluble

Explanation:

 The oxygen (O2) and the carbon dioxide (CO2) are easily pass through the plasma membrane as both the molecules are soluble and exist in non polar form. These both types of molecules can move through the plasma membrane by the simple diffusion.

By using the simple diffusion the structure of lipid basically allow the oxygen, carbon dioxide and either uncharged substance can easily pass though the plasma membrane.

Therefore, Option (A) is correct.
