$\begin{array}{|l|l|r|l|}\hline & \text{List-I} & & \text{List-II} \\ \hline A. & \text{Primary structure of protein} & III. & \begin{array}{l} \text{Polypeptide chain with positional information of amino} \\ \text{acids} \end{array} \\ \hline B. & \text{Secondary structure of protein} & IV. & \text{Alpha helix and } \beta \text{ sheet structure} \\ \hline C. & \text{Tertiary structure of protein} & II. & \begin{array}{l} \text{Hollow woolen ball like structure with hydrogen and} \\ \text{disulphide bonds} \end{array} \\ \hline D. & \text{Quaternary structure of protein} & I. & \begin{array}{l} \text{Assembly of more than one polypeptides, seen in adult} \\ \text{human haemoglobin} \end{array} \\ \hline \end{array}$

Hence, A-III, B-IV, C-II, D-I is the correct match.
