B
C, H, O, N
C
C, H, O, N, P
D
C, H, O, N, S, Ca
Explanation: 

Detailed explanation-1: -Proteins are found in all living organisms and are composed of molecules called amino acids. Each amino acid contains four elements they are hydrogen, oxygen, nitrogen and carbon and in certain cases may also contain sulfur.

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.

Detailed explanation-3: -Proteins are made of carbon, hydrogen, oxygen, and nitrogen (CHON). Nucleic acids such as DNA and RNA contain carbon, hydrogen, oxygen, nitrogen, and phosphorus (CHON P).

Detailed explanation-4: -The building blocks of proteins are amino acids, which are small organic molecules that consist of an alpha (central) carbon atom linked to an amino group, a carboxyl group, a hydrogen atom, and a variable component called a side chain (see below).

Detailed explanation-5: -Proteins differ from carbohydrates and lipids in that, they always contain nitrogen, carbon, hydrogen and oxygen.
