Which of the following is a good iron source among beans?

• A. Kidney beans
• B. White rice
• C. Butter
• D. Banana

Answer: (A)

The main idea is identifying a solid plant-based iron source among common foods. Kidney beans provide a meaningful amount of iron per cooked serving, and they’re a true bean, so they’re a good option for boosting iron intake on a vegetarian or vegan diet. The iron in beans is non-heme iron, which is absorbed less efficiently than the iron in animal foods, but you can improve absorption by pairing with vitamin C-rich foods (like citrus or peppers) and by soaking or cooking to reduce compounds that inhibit absorption. White rice is a grain with lower iron density and isn’t a bean; butter has negligible iron; banana contains only trace iron. So kidney beans are the best choice here for a good iron source among the options.
