Answer:

C. third

Explanation:

A protein has four levels of structure:

  1. First: conformed by the linear sequence of amino acids linked by peptide bonds.
  2. Secondary:  is the folding of the polypeptide chain and it cam have two shapes: α-helix and the β-pleated sheet.
  3. Third: is the spatial arrangement of amino acids after they form the α-helix and the β-pleated sheet.
  4. Fourth: when a protein is formed by different polypeptide chains
