Answer 1

(B) is the correct answer.

1. Cells exchange gases through the process of diffusion.
2. This process is characterized by movement of molecules from region of higher concentration to lower concentration, along the concentration gradient.
3. This further helps in not requiring energy hence making it a passive process.
4. Common example of gaseous exchange in cells is in blood, where oxygen and carbon dioxide are exchanged with organs.
