Which of the following is an important source of Vitamin-E?

Wheat germ oil is the classic answer, and among these four options it is the richest source of vitamin E. Vitamin E is a group of fat-soluble compounds, tocopherols and tocotrienols, and alpha-tocopherol is the most biologically active form. Wheat germ oil carries a high concentration of it, which is why standard nutrition texts cite it as the main source.

Why the others are weaker choices:

• Palm oil: Crude and red palm oil contain tocotrienols, but refining removes a substantial part of them, so it is not the standard answer.
• Coconut oil: Very low in vitamin E. Its fat is mostly medium-chain saturated fat, not a meaningful carrier of the vitamin.
• Mustard oil: Contains some tocopherols, but it is not recognised as an important source in standard nutrition tables.

Core concept: fat-soluble vitamins (A, D, E, K) and their dietary sources. Mains angle: micronutrient deficiency and food fortification, linked to nutrition schemes such as POSHAN Abhiyaan.

Trap: picking palm oil because it is often mentioned as a vitamin E source in general discussions. In the exam, go by the textbook source list.
