A
Osmosis

B
Diffusion

C
Active transport

D
All of the above

Solution

The correct option is B All of the above
Diffusion is the transport according to the concentration gradient. Gaseous exchange takes place through diffusion. Osmosis is diffusion of solvent across a semi-permeable membrane. It also follows the concentration gradient. Uptake of solvent by plant cells is an example. Active transport requires energy expenditure and occurs against concentration gradient. 
Thus, the correct answer is option D.
