A
calcium
B
nitrogen
C
chlorine
D
sodium
Explanation: 

Detailed explanation-1: -Protein is mainly formed by carbon, hydrogen, nitrogen and oxygen. Amino acids join to form proteins. Each amino acid is formed with one basic group NH2 and one acidic group(COOH).

Detailed explanation-2: -In addition to carbon, hydrogen, and oxygen atoms, all proteins contain nitrogen and sulfur atoms, and many also contain phosphorus atoms and traces of other elements. Proteins serve a variety of roles in living organisms and are often classified by these biological roles.

Detailed explanation-3: -Proteins contain carbon, hydrogen, oxygen, nitrogen, and sulfur. A protein molecule is made from one or more long chains of amino acids, each linked to its neighbors by covalent bonds. Multiple chains of a protein are held together by weaker bonds. Proteins are the most numerous and diverse biochemical compounds.

Detailed explanation-4: -nitrogen is needed with carbon, hydrogen and oxygen to make protein.

Detailed explanation-5: -Proteins are compounds composed of carbon, hydrogen, oxygen, and nitrogen, which are arranged as strands of amino acids .
