The difference in size of particles is used to separate them by the process of :
The correct options is D, both filtration and sieving.
Explanation for the correct option
In both the process of filtration and sieving, the difference in size of the particle is used to separate the constituents parts.
Sieving: Sieving is a simple and convenient technique of separating particles of different sizes. A small sieve such as that used for sifting flour has very small holes which allow only very fine flour particles to pass through.
Filtration: Filtration is the process of separating suspended solid matter from a liquid, by causing the latter to pass through the pores of some substance, called a filter. The liquid which has passed through the filter is called the filtrate.
Explanation for the incorrect option
(A) Winnowing - It is a process where heavier components are separated for lighter substance with the help of air. It is employed in separating grain from chaff.
