Since, the options are not given the question is incomplete. The complete question is as follows:

Water movement from the side of the membrane having a lesser number of particles and greater concentration of water to the side having a greater number of particles and lesser concentration of water is termed?

a) osmosis

b) active transport

c) filtration

d) diffusion

Answer: A). Osmosis

Explanation:

Osmosis is a process which occurs in between the two solution gradients separated by a semi-permeable membrane like a cell membrane. In this process the molecules present in the solvent moves from less concentrated solution to a more concentrated solution. This is to equalize the concentration of solutes on both sides.
