A

To match the terms in List-I with List-II:
A. Saturated solution corresponds to IV because a saturated solution is one that contains the maximum amount of solute at a given temperature.
B. Binary solution refers to III as a binary solution is specifically a solution consisting of two components.
C. Isotonic solution relates to I where isotonic solutions have the same osmotic pressure at a given temperature.
D. Hypotonic solution matches with II for solutions whose osmotic pressure is less than that of another solution.
Thus, the correct match is: A-IV, B-III, C-I, D-II. Therefore, option A is correct.
