Correct Answer
(A) (A)-(IV), (B)-(I), (C)-(II), (D)-(III)
Solution & Explanation
Answer: (A) (A)-(IV), (B)-(I), (C)-(II), (D)-(III). Solution: Each biomolecule class is matched to its characteristic bond/feature. (A) Proteins are polypeptides linked by peptide bonds — (IV). (B) Unsaturated fatty acids contain C=C double bonds — (I). (C) Nucleic acids are polynucleotides whose nucleotides are joined by phosphodiester bonds — (II). (D) Polysaccharides are chains of sugars linked by glycosidic bonds — (III). This gives A-IV, B-I, C-II, D-III. NCERT Reference: Ch 9, p.109, line ~40 — "Proteins are polypeptides. They are linear chains of amino acids linked by peptide bonds"
