Question

Match List-I with List-II:

• A. A-I, B-II, C-IV, D-III
• B. A-I, B-II, C-III, D-IV
• C. A-I, B-III, C-II, D-IV
• D. A-III, B-IV, C-I, D-II

Answer 1

The Correct Option is A

Accurate matching of List-I with List-II requires an understanding of the distinct characteristics, functions, and locations of fibrous proteins.

List-I	List-II
A. Keratin	I. Structural protein in hair and nails
B. Collagen	II. Fibrous protein of connective tissues
C. Fibroin	IV. Protein component of silk
D. Elastin	III. Imparts elasticity to tissues

The following correspondences are established based on these properties:

• Keratin, a structural protein essential for hair and nails, corresponds to I.
• Collagen, a fibrous protein predominantly in connective tissues, matches II.
• Fibroin, the protein comprising silk, aligns with IV.
• Elastin, crucial for tissue elasticity, corresponds to III.

Therefore, the correct pairings are: A-I, B-II, C-IV, D-III.
