Answer:
Correct Answer: 27. $( \mathrm{A} \rightarrow \mathrm{p}, \mathrm{s} ; \mathrm{B} \rightarrow \mathrm{q}, \mathrm{r} ; \mathrm{C} \rightarrow \mathrm{p}, \mathrm{r} ; \mathrm{D} \rightarrow \mathrm{s} )$
Solution:
(A) Cellulose-a natural polymer of $\alpha$-D-glucose, linked by glycoside linkage.
(B) Nylon-$6,6$ -a synthetic polymer of adipic acid and $1,6$-diaminohexane. The diacid is linked with diamine through amide linkage.
(C) Protein-a natural polymer of $\alpha$-amino acids where individual amino acid units are linked by amide linkage.
(D) Sucrose-has glycoside linkage, a disaccharide.
