A Correct answer
Explanation

Fish is a complete protein source because it contains all nine essential amino acids that the human body cannot synthesize on its own. Complete proteins are primarily found in animal products like meat, fish, eggs, and dairy. Bread and dried beans are incomplete proteins on their own, though beans can be combined with grains to form complete proteins.
