A Correct answer
Explanation

Soyabean is exceptionally rich in protein (~40% by weight), containing all essential amino acids, making it a complete protein source. This is why it's called the 'meat of the field' or 'poor man's meat'. While soy contains vitamins and minerals, its protein content is what distinguishes it from other plant sources.
