The correct option is D Only C and D
Diffusion is a process of movement of substances from a region of its higher concentration to a region of its lower concentration. Among the options listed, only options C and D occur due to diffusion alone at all times. Movement of water along the concentration gradient through a membrane (semi-permeable) is called osmosis and the movement of minerals from the soil into root hairs happens as a result of active transport.
