Why should grains be dried before storage?

Grains be dried before storage to remove moisture from them.

Grains can be defined as the edible seeds of plants that belong to the Poaceae family. These grains are also called cereals or cereal grains. Some of the commonly consumed grains include wheat, oats and rice. The process of drying the grain before storing it involves exposure to sunlight and keeping it in an environment of relatively low humidity that helps in the removal of moisture from the grain. After harvesting the grains, they need to be stored for a certain amount of time before they are sold to the consumers. If the grains contain a high level of moisture, there is a higher possibility that they would develop fungal growth that would lead to the spoilage of the entire stock of grains. Hence it is important to dry the grains before storing them. 

Hence, the correct option is A.
