Match List I with List II:
| List I | List II |
|---|---|
| a. Tocopherol | I. Vitamin K1 |
| b. phylloquinine | II. Vitamin B12 |
| c. Retinol | III. Vitamin E |
| d. Cyanocobalamin | IV. Vitamin A |
Choose the correct answer from the options given below:
Answer: D
The correct match is a-III, b-I, c-IV, d-II.
- Tocopherol is vitamin E.
- Phylloquinone (spelt 'phylloquinine' in the paper) is vitamin K1, the plant form of vitamin K.
- Retinol is vitamin A.
- Cyanocobalamin is vitamin B12, which contains cobalt.
The first option swaps K1 and B12, and the other two misplace tocopherol, so only the fourth puts every chemical name with its vitamin.
