Solution
The correct option is B Threshing
(a) Handpicking is used for separating slightly larger-sized impurities such as pieces of dirt, stones, husk from wheat, rice, pulses, etc. by hand.
(b) Winnowing is the process of separating heavier and lighter components of a mixture by wind or by blowing air.
(c) Sieving is the process of separating fine particles from larger particles by using a sieve.
(d) Threshing is the process of separating seeds from their chaffs in the harvested crops.
So, threshing is the most appropriate technique for separating grains from their stalks.
