A

(a) - (iii), (b) - (ii), (c) - (iv), (d) -(i)

B

(a) - (iii), (b) - (iv), (c) - (i), (d) -(ii)

C

(a) - (iv), (b) - (iii), (c) - (i), (d) -(ii)

D

(a) - (iii), (b) - (iv), (c) - (ii), (d) -(i)

Solution

## The correct option is D (a) - (iii), (b) - (iv), (c) - (i), (d) -(ii) The solid-liquid mixture (insoluble solid):- Filtration is a separation technique that is used to separate the components of solid-liquid mixture i.e. an insoluble solid substance from a liquid. The liquid-liquid mixture (miscible liquids):- Distillation is a separation technique that is used to separate the components of a liquid-liquid mixture in which both the liquids are miscible with each other and difference in their boiling points is more than 25 ∘C. The solid-solid mixture (one component is more volatile):- Sublimation is a separation technique that is used to separate the components of the solid-solid mixture in which one solid component is more volatile than other. The liquid-liquid mixture (immiscible liquids):- Separating funnel is a separation technique that is used to separate the components of the liquid-liquid mixture in which both the liquids are immiscible with each other and can be separated on the difference in their densities.
