Which of the following is NOT a coarse grain?

Wheat is classified as a fine grain rather than a coarse grain, which is why it is the correct answer to the question. Coarse grains typically include plants that have a larger, more robust kernel structure, which is common in grains like corn and sorghum. These grains are often referred to as "cereal grains" and are used primarily for animal feed and industrial uses due to their high starch content.

In contrast, wheat is primarily cultivated for its flour and is milled into various products like bread and pasta. While wheat does contain starch, its end uses and kernel structure categorize it differently from coarse grains. Understanding the distinction between coarse and fine grains is essential in agricultural practices and crop insurance, as it influences factors like market demand and risk management associated with different types of crops.
