Oil derived from fish, used for health benefits, is which?

• A. Cod-liver oil
• B. Fish oil
• C. Linseed oil
• D. Olive oil

Answer: (A)

Cod-liver oil is a fish-derived oil that has long been used for health benefits because it comes from the liver of cod and provides essential nutrients, notably vitamins A and D along with omega-3 fatty acids. This combination has made it a classic dietary supplement in many health contexts. The other oils listed aren’t from fish: linseed oil comes from flax seeds and olive oil from olives, so they don’t fit the “oil derived from fish” idea. While fish oil in general is used for health benefits, cod-liver oil stands out as the specific fish-derived option traditionally associated with nutritional supplementation.
