Vitamins are compounds our bodies need in small amounts, that we cannot produce ourselves. Having enough of each is essential to staying healthy; having a deficiency can result in disease. There can also be a danger in getting too much of a vitamin, especially the fat-soluble vitamins (A, D, E, and K)--they can accumulate in the body's fat stores and become toxic. Vitamins B and C are water-soluble, and excess of these two is usually eliminated with urine.
Good dietary sources of vitamin A are greens, orange, and yellow vegetables. There are several types of B vitamins. They are found in meat/fish, eggs, and dairy products, as well as plants such as bananas and greens. B-12 is found only in animal products, so someone who is vegan has to be careful to take a supplement. Vitamin C is famously found in citrus fruits, but also in kiwi, tomatoes, greens, and potatoes. Vitamin E is found in vegetable oils and seeds, and greens. If your question is meant as to what type of food contains all four of those vitamin types, greens would be a good choice.
I'm not sure if you meant to ask about vitamin D, but it is found in fatty fish. Milk in the US is fortified (supplemented) with vitamin D, as it doesn't occur naturally in too many foods. Sunlight helps the body to produce vitamin D.
