Correct answer
BA-IV, B-I, C-II, D-III

Step-by-step explanation

Glutamine contains an amide group in its side chain, which gives a positive Hoffmann bromamide degradation test. Thus, A matches IV.

Lysine contains a primary amine group in its side chain, which gives a positive Hinsberg's test. Thus, B matches I.

Tyrosine contains a phenolic hydroxyl group in its side chain, which gives a positive neutral test. Thus, C matches II.

Serine contains an alcoholic hydroxyl group in its side chain, which gives a positive ceric ammonium nitrate test. Thus, D matches III.

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

Answer: A-IV, B-I, C-II, D-III
