Solution

The correct option is D increasing the number of solute molecules
Osmotic pressure is the minimum pressure which needs to be applied to a solution to prevent the inward flow of its pure solvent across a semipermeable membrane.it is also defined as the measure of the tendency of a solution to take in pure solvent by osmosis.

osmosis is an example of of diffusion, which is when molecules tend to distribute themselves evenly in a space.
