Match List-I and List-II

List-I	List-II
A. Osmosis	I. Solvent molecules pass through semi permeable membrane towards solvent side.
B. Reverse osmosis	II. Movement of charged colloidal particles under the influence of applied electric potential towards oppositely charged electrodes
C. Electro osmosis	III. Solvent molecules pass through semi permeable membrane towards solution side
D. Electrophoresis	IV. Dispersion medium moves in an electric field.

Choose the correct answer from the options given below:

We need to match List-I with List-II regarding osmosis-related phenomena.

A. Osmosis: The spontaneous flow of solvent molecules through a semi-permeable membrane from pure solvent (or dilute solution) towards the solution side.

This matches with III: Solvent molecules pass through semi permeable membrane towards solution side.

B. Reverse osmosis: When external pressure greater than osmotic pressure is applied, solvent molecules move from solution side to solvent side through the membrane.

This matches with I: Solvent molecules pass through semi permeable membrane towards solvent side.

C. Electro osmosis: The movement of dispersion medium (solvent) under the influence of an applied electric field through a membrane.

This matches with IV: Dispersion medium moves in an electric field.

D. Electrophoresis: The movement of charged colloidal particles under the influence of applied electric potential towards oppositely charged electrodes.

This matches with II: Movement of charged colloidal particles under the influence of applied electric potential towards oppositely charged electrodes.

The correct matching is: A-III, B-I, C-IV, D-II

The correct answer is Option B: A-III, B-I, C-IV, D-II.

The recorded answer is Option D (code 4): A-I, B-III, C-II, D-IV. However, osmosis is movement towards solution side (not solvent side), so A should match III. Our answer (Option B) is correct. Saving for review.
