Answer

Brief Explanations:

A polypeptide is a chain of amino - acids linked by peptide bonds. The first option is a di - peptide (two amino - acids linked), the second is a single amino - acid, and the third is a longer chain of amino - acids (a polypeptide).

Answer:

The third structure (the longest chain of amino - acids linked by peptide bonds)
