The correct answer is option 1, vitamin A. Carrots are indeed a rich source of vitamin A. Vitamin A is important for good vision, as it helps to maintain the health of the eyes and improve night vision. It also plays a vital role in maintaining healthy skin and supporting the immune system. Carrots are also rich in beta-carotene, which is a precursor to vitamin A. When we consume beta-carotene, our body converts it into vitamin A. This is why carrots are often recommended for improving vision and promoting overall health. It`s important to note that while carrots are a great source of vitamin A, they also contain other beneficial vitamins and minerals.
