D

Structure of proteins is characterised into primary, secondary, tertiary, and Quaternary structures.

Explanation:

Primary structure is merely the sequence of amino acids after translation. The secondary structure of proteins is formed from the interactions of the carbonyl, amino, and side groups of the amino acid polymer backbone within the chain. These interactions are mainly   driven by hydrogen bonding that forms alpha-helices and beta-sheets structures where are the main characteristic of secondary structure of proteins.  

Tertiary structure involves more interactions within the protein chain to form a functional 3D structure. These interactions include disulfide bonds between cysteines, hydrophobic interactions, ionic bonding, and dipole-dipole interactions. Quaternary structure involves interaction between multiple protein chains to form a functional 3D protein structure.
