Answer: (A)

Verified step by step guidance

1. Step 1: Understand the concept of osteoporosis. Osteoporosis is a condition characterized by weakened bones, making them more prone to fractures. Risk factors include dietary deficiencies, hormonal changes, age, and lifestyle factors.
2. Step 2: Review the role of nutrients in bone health. Key nutrients for bone health include calcium, vitamin D, and phosphorus. Vitamin A, while important for overall health, is not directly linked to osteoporosis risk when consumed in appropriate amounts.
3. Step 3: Analyze each option provided in the question. Evaluate how each factor contributes to osteoporosis risk. For example, lack of physical activity can lead to weaker bones, being female is associated with hormonal changes post-menopause, and aging (over 65 years) increases bone loss.
4. Step 4: Compare the role of vitamin A to other factors. While excessive vitamin A intake may negatively impact bone health, a diet low in vitamin A is not a recognized risk factor for osteoporosis compared to the other options listed.
5. Step 5: Conclude that the correct answer is the option that does not align with established risk factors for osteoporosis. In this case, 'A diet low in vitamin A' is not a significant risk factor for osteoporosis compared to the other options.
