Which of the following pairs is NOT correctly matched? (Vitamin) : (Rich Source)

The mismatch is Vitamin B2 (riboflavin) : Cod-liver oil. Cod-liver oil is a classic source of fat-soluble vitamins, mainly A and D, not a B-complex vitamin. Riboflavin comes from milk and dairy, eggs, liver, meat, and green leafy vegetables.

The other three pairs are correct:

• Vitamin B6 : Rice bran. Rice bran is a good source of B-complex vitamins, including B6 (pyridoxine).
• Vitamin E : Wheat germ oil. Wheat germ oil is one of the richest natural sources of tocopherols, the antioxidant form of vitamin E.
• Vitamin K : Alfalfa. Alfalfa and green leafy vegetables are important sources of vitamin K1, which is needed for blood clotting.

The core concept is the split between fat-soluble (A, D, E, K) and water-soluble (B-complex, C) vitamins, and knowing their dietary sources. For Mains (GS-II and GS-III), this links to micronutrient deficiency, food fortification and nutrition programmes such as POSHAN Abhiyaan.

Trap: Candidates mark the vitamin A/D source as the B-vitamin source because cod-liver oil is strongly associated with 'vitamins' in general. Check whether the vitamin itself belongs to the fat-soluble or water-soluble group.
