Answer 1

The correct option is B

(i) and (iii) are correct

• Wind winnowing is an agricultural method developed by ancient cultures for separating grain from chaff.
• It is also used to remove weevils or other pests from stored grain.
• In its simplest form, it involves throwing the mixture into the air so that the wind blows away the lighter chaff, while the heavier grains fall down for recovery.
• The process of loosening of grains or seeds from the husks and straw is called threshing. It is a preliminary step in chaff removal, which is done before winnowing.
• There is no fodder loss in the process of traditional winnowing. However, modern equipment used for threshing cause subsequent fodder loss.
