Citrus fruits are particularly rich in Vitamin C, which is critical for several bodily functions. Vitamin C, also known as ascorbic acid, plays a vital role in the synthesis of collagen, the healing of wounds, and the maintenance of cartilage, bones, and teeth. It is also a powerful antioxidant, helping to protect cells from damage by free radicals. Because of these health benefits, fruits like oranges, lemons, limes, and grapefruits are commonly recommended as excellent sources of this essential vitamin.

In contrast, Vitamin A is more commonly found in foods like carrots and leafy greens, whereas Vitamin B12 is primarily found in animal products and is necessary for red blood cell production and neurological function. Additionally, Vitamin D, which supports bone health and immune function, can be obtained from sun exposure and foods like fatty fish and fortified dairy products, rather than from citrus fruits. Thus, the strong presence of Vitamin C in citrus fruits clearly distinguishes it as the correct answer.
