To match List-I with List-II correctly, we need to understand the characteristics and associations of fibrous proteins and their functions.
| List-I | List-II |
|---|
| A. Keratin | I. Structural protein found in hair and nails |
| B. Collagen | II. Fibrous protein in connective tissues |
| C. Fibroin | IV. Protein found in silk |
| D. Elastin | III. Provides elasticity to tissues |
Based on the properties and locations of these proteins, we can establish the following associations:
- Keratin is a structural protein important for hair and nails, aligning with I.
- Collagen is a fibrous protein primarily found in connective tissues, matching with II.
- Fibroin is known as the protein found in silk, so it matches with IV.
- Elastin provides elasticity and is significant for tissues, aligning with III.
Thus, the correct matching sequence is: A-I, B-II, C-IV, D-III.
