The correct matching is as follows:
- A. Starch is made up of \( \alpha \)-glucose, so \( A - II \).
- B. Cellulose is made up of \( \beta \)-glucose, so \( B - III \).
- C. Nucleic acid is made up of nucleotides, so \( C - I \).
- D. Protein is made up of amino acids, so \( D - IV \).
Hence, the correct matching is \( A - II, B - III, C - I, D - IV \).
The Correct Answer is: \( A - II, B - III, C - I, D - IV \)
