Colligative properties are observed when a non-volatile solid or liquid are dissolved in a volatile liquid.

This is a multiple choice answer as classified in NCERT Exemplar

(i) and (iv)

Explanation : Because the slopes in (i) and (iv) are straight lines, they represent the solution's ideal behaviour.

(ii) and (ii) 

Isotonic solutions must have same osmotic pressure at a given temperature hence must have same volume and number of moles i.e., same molar concentration. Thus, the isotonic solutions have same elevation in boiling point, and depression in freezing point.

This is a multiple choice answer as classified in NCERT Exemplar

(i) and (ii)

Explanation: Colligative property depends on

(i) The concentration of a nonelectrolyte solute in solution,

(ii) The number of particles of electrolyte solute in solution, & (iii) It does not depend on the nature of solute molecules/particles.
