GENERAL KNOWLEDGE

Detailed explanation-1: -The correct answer is Fish. Proteins are the building blocks of life. Every cell in the human body contains protein. The basic structure of a protein is a chain of amino acids.

Detailed explanation-2: -Animal-based foods (meat, poultry, fish, eggs, and dairy foods) tend to be good sources of complete protein, while plant-based foods (fruits, vegetables, grains, nuts, and seeds) often lack one or more essential amino acid.

Detailed explanation-3: -Fresh tuna has the most protein per gram of any of the seafood on this list. With 30.7g of protein in a 100-gram serving, fresh tuna has the most protein by weight and is at the top of the list of commercially available, high-protein fish.

Detailed explanation-4: -Fish and shellfish are excellent sources of protein. A 100 g cooked serving of most types of fish and shellfish provides about 18–20 g of protein, or about a third of the average daily recommended protein intake.
