Verified step by step guidance

Step 1: Understand the role of vitamins in bone growth. Bone growth and maintenance require specific nutrients, including vitamins, minerals, and proteins. Vitamins play a crucial role in processes like calcium absorption, collagen synthesis, and bone mineralization.

Step 2: Review the function of Vitamin D. Vitamin D is essential for calcium absorption in the intestines and maintaining adequate serum calcium and phosphate levels, which are necessary for normal bone mineralization. Without sufficient Vitamin D, bones can become thin, brittle, or misshapen.

Step 3: Compare the roles of other vitamins listed in the problem. Vitamin B12 is primarily involved in red blood cell formation and neurological function. Vitamin K is important for blood clotting and also plays a minor role in bone health by regulating calcium in the bones and blood. Vitamin C is crucial for collagen synthesis, which is a structural protein in bones, but it is not directly responsible for calcium absorption or bone mineralization.

Step 4: Identify the vitamin that directly supports bone growth. Based on the functions described, Vitamin D is the vitamin specifically required for normal bone growth due to its role in calcium absorption and bone mineralization.

Step 5: Conclude that Vitamin D is the correct answer, as it is uniquely essential for the processes that directly contribute to normal bone growth and maintenance.
