The correct answer is (c). Lemons are a good source of vitamin C. They also contain small amounts of other vitamins and minerals, including potassium, folate, and thiamin.
Vitamin C is a water-soluble vitamin that is essential for human health. It is involved in many important bodily functions, including the production of collagen, the absorption of iron, and the maintenance of a healthy immune system. Vitamin C is also a powerful antioxidant, which means that it can help protect cells from damage caused by free radicals.
The recommended daily intake of vitamin C for adults is 90 milligrams. A single lemon contains about 31 milligrams of vitamin C, so eating one lemon a day can help you meet your daily requirement.
In addition to lemons, other good sources of vitamin C include oranges, grapefruit, strawberries, broccoli, and tomatoes.
