List II	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 :

• A. A-I, B-III, C-IV, D-II
• B. A-III, B-I, C-IV, D-II
• C. A-III, B-I, C-II, D-IV
• D. A-I, B-III, C-II, D-IV

Answer 1

The Correct Option is B

To solve this question, we need to match the concepts listed in List I with their correct descriptions in List II. Let's analyze each term one by one:

1. Osmosis: Osmosis is the movement of solvent molecules through a semi-permeable membrane from a less concentrated solution to a more concentrated solution. Therefore, the correct match is "Solvent molecules pass through a semi-permeable membrane towards solution side." Hence, A matches with III.
2. Reverse Osmosis: In reverse osmosis, the process is reversed by applying pressure on the solution side, causing solvent molecules to pass through a semi-permeable membrane towards the pure solvent. Therefore, B matches with I.
3. Electro-Osmosis: This is the movement of the dispersion medium under the influence of an electric field. Therefore, C matches with IV.
4. Electrophoresis: Electrophoresis involves the movement of charged colloidal particles under an applied electric potential towards oppositely charged electrodes. Therefore, D matches with II.

After analyzing all the terms, the correct match is:

• A - III
• B - I
• C - IV
• D - II

Therefore, the correct answer is A-III, B-I, C-IV, D-II.
