Why do o2 and co2 pass through the plasma membrane? a. they are nonpolar and soluble b. they are facilitated by protein c. they are "pumped" through d. they undergo pinocytosis

(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.
