Thiamine, also known as Vitamin B1, is an essential micronutrient that plays multiple roles in the proper functioning of our bodies. It primarily helps in converting carbohydrates into energy, supporting our nervous system, and maintaining a healthy heart. While other vitamins are classified under options A, C, and D, Thiamine is specifically grouped under B due to its unique chemical and biological properties. Therefore, option B is the correct answer for this question. Additionally, option A is incorrect because vitamin A, or retinol, has a different chemical structure and functions for our immune system and vision. Option C, vitamin C, is incorrect because it is a water-soluble vitamin that helps in collagen production and supports our immune system function. Option D, vitamin D, is incorrect because it is a fat-soluble vitamin that plays a crucial role in bone health and maintaining calcium levels in our body. Hence, Thiamine is classified under option B, Vitamin B1.
