Solution
The correct option is B Winnowing Winnowing can be used to remove lighter particles of fodder from grains. In winnowing the lighter particles of one substance get separated from comparatively heavier particles of another substance with the help of wind.
Winnowing is done in the direction of air so that the lighter particles get blown away by the air leaving behind only heavier particles.
