Answer: (B)

Verified step by step guidance

1. Understand the difference between micronutrient deficiencies and other causes of disorders. Micronutrients include vitamins and minerals required in small amounts for proper body function.
2. Analyze each disorder to identify if it is caused by a lack of a micronutrient: Lactose intolerance is due to an enzyme deficiency, not a micronutrient deficiency.
3. Scurvy is caused by a deficiency of vitamin C, which is a micronutrient, making it directly related to a micronutrient deficiency.
4. Hypertension is often related to excessive sodium intake, which is a macronutrient/mineral imbalance rather than a deficiency.
5. Type 1 diabetes mellitus results from autoimmune destruction of pancreatic beta cells, not from a micronutrient deficiency.
