​Which among the following micronutrients is essential for the normal functioning of the thyroid gland?​

Correct option is C

The correct answer is (C) Iodine.

Explanation:

• Iodine is essential for the production of thyroid hormones, which regulate metabolism and growth. Its deficiency can cause goiter and other thyroid-related disorders.

Incorrect Options Explanations:

• Potassium: Important for nerve and muscle function but not directly related to the thyroid gland.
• Calcium: Essential for bone health and muscular function, not thyroid activity.
• Iron: Crucial for hemoglobin production but not linked to thyroid function.

Information Booster:

• Iodine deficiency can lead to conditions like hypothyroidism and goiter.
• Foods rich in iodine: iodized salt, seafood, and dairy products.
• Thyroid hormones regulated by iodine: Thyroxine (T4) and Triiodothyronine (T3).
