Primary structure.

Explanation:

Because primary structure refers to the sequence of amino acids in a particular polypeptide chain. And the changes in pH mostly affects:

  • Hydrogen bonds between side chains(R) of amino acids.
  • Salt briges which are non-covalent interactions present between oppositely charged side chains(R) of amino acids.

Thus, primary structure constituting amino acid sequence are least susceptible to denaturation by change in pH.
