Which of the following is classified as a small grain?

Wheat is classified as a small grain because it belongs to the category of grasses that are cultivated mainly for their seeds. Small grains typically refer to cereal crops that are harvested for their grain, and wheat is one of the most common examples of this classification. This designation includes grains that are smaller in size and are used primarily for food, feed, and other products.

In the case of corn and soybeans, these are classified differently due to their larger seed size and their categorization as broadleaf plants rather than grasses. Corn is considered a large grain and belongs to the family of grasses but is distinct from small grains like wheat. Soybeans, being a legume, also do not fall into the small grains category. Rye, while technically a small grain, is often not the primary example used for this classification in certain contexts, where wheat is emphasized. Hence, wheat stands out clearly as the archetypal small grain in this scenario.
