Answer:
Option (A)
Explanation:
Diffusion is defined as the transfer of particles such as ions or molecules from a higher concentration region to a lower concentration region.
Osmosis is a special type of diffusion in which the solvents such as water are allowed to move from a region of higher to a lower concentration through a layer of a semi-permeable membrane. This is an energy-independent process and occurs along the concentration gradient.
Thus, the correct answer is option (A) that is true for both osmosis and diffusion.
