Which of the following is a mineral deficiency disease?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. Goitre.
Goitre is a mineral deficiency disease caused by a lack of iodine in the diet. Iodine is essential for the production of thyroid hormones, which regulate growth, metabolism, and development. When iodine is deficient, the thyroid gland enlarges, forming a visible swelling in the neck. Goitre can lead to symptoms like fatigue, weight changes, and developmental issues in severe cases. It is commonly prevented by consuming iodised salt and iodine-rich foods like seafood and dairy products. Unlike goitre, marasmus, rickets, and scurvy are caused by protein, vitamin D, and vitamin C deficiencies, respectively.
