1. Legume
2. Rice
3. Wheat
4. Corn

Answer 1

Correct Answer - Option 1 : Legume

The Correct Answer is Legume.

• Legume, also called a pod, the fruit of plants in the pea family (Fabaceae). 
• Most legumes are dehiscent fruits that release their seeds by splitting open along two seams, though some, such as peanuts and carobs, do not naturally open. 
• The fruits come in a variety of sizes and shapes; many, however, are long and narrow and bear their seeds in a single line. 

• Rice is the seed of the grass species Oryza sativa or less commonly Oryza glaberrima. As a cereal grain, it is the most widely consumed staple food for a large part of the world's human population, especially in Asia and Africa.
• Wheat is a grass widely cultivated for its seed, a cereal grain which is a worldwide staple food. The many species of wheat together make up the genus Triticum; the most widely grown is common wheat.
• Maize, also known as corn, is a cereal grain first domesticated by indigenous peoples in southern Mexico about 10,000 years ago.
