Answer 1

Answer: (B), (C), (D)

To protect them from pests.

Grain production is seasonal but its consumption is continuous. They have to be protected from unfavourable weather, moulds, harmful microorganisms, moisture, insects, rodents, birds and other contaminants. Hence, in order to maintain grain quality and quantity for long periods, storage of grains require chemical treatment which protects them from pests, microorganisms and moisture.
