according to t Fick`s first law the diffusion flux is directly proportional to the concentration gradient.
diffusion flux (J) is the material pass across the unit area per unit time.
J=-DdC/dx
D is the diffusion coefficient and dC/dx= concentration gradient so the answer is a) is directly proportional to the concentration gradient.
