• A. Sieving
• B. Filtration
• C. Decantation

Answer 1

The correct option is B

Filtration

Explanaion for the correct option:

(B) Filtration

• Filtration is the process of removing solid particles from liquid or gaseous fluids by passing the fluid through a filter media while keeping the solid particles behind.
• The intended product might be either the fluid that has been cleared or the fluid that has had its solid particles removed.
• Tea leaves can be easily separated from tea by filtration.

Explanation for the incorrect option:

(A) Sieving

• Using a sieve to separate tiny particles from larger ones is known as sieving.
• It is applied on construction sites or grain mills.
• At the flour mill, impurities like husks and stones are removed from the wheat.
• By sieving, they separate the stones and pebbles from the sand.

(C) Decantation

• By removing the liquid layer at the top from the layer of solid or liquid below.
• Decantation is the process of separating liquid from solid and other immiscible (non-mixing) liquids.
• After pouring away the top layer, the mixture can be tilted to complete the process.

Hence, the correct option is (B) Filtration.
