Q. Consider the following statements regarding the physical principles governing the movement of molecules:

Statement I: Force represents the driving tendency for a physical or chemical process.

Statement II: A concentration difference induces the movement of molecules from a region of low concentration toward a region of high concentration.

Statement III: The concentration gradient serves exclusively as the driving force for active transport.

Statement IV: During diffusion, molecules spontaneously move from a region of high concentration to a region of low concentration due to the existing concentration gradient.
