Answer 2

Tip- To separate the helpful components from the non-useful or potentially hazardous components, we must separate the various components of a mixture.

Winnowing is the technique of separating heavier and lighter components of a mixture using wind or blowing air.

Explanation: The winnowing procedure can be used to separate husk or soil particles. Wind or blowing air is used to separate the heavier and lighter components of a combination.

This approach involves placing a mixture of husk and grain seeds on a plate and allowing them to fall from a height up to our shoulders. The lighter husk is removed by blowing air as the mixture descends, and the heavier grain seeds fall to form a heap.

Hence, Option 4(winnowing) is correct
