​The disorder of goiter is caused due to the deficiency of:​

Correct option is A

The correct answer is (A) iodine.​

• Goiter is a condition characterized by the enlargement of the thyroid gland, which is located in the neck.
• This disorder is primarily caused due to the deficiency of iodine, an essential element required for the production of thyroid hormones. When iodine is lacking in the diet, the thyroid gland works harder to produce these hormones, leading to its enlargement (goiter).
• Iodine deficiency is a significant health issue in many regions where iodine-rich foods (like seafood and dairy products) are not readily available.

Information Booster:

• Calcium: Calcium deficiency leads to conditions like rickets and osteoporosis, not goiter.
• Potassium: Potassium deficiency can lead to muscle weakness and cramping, not goiter.
• Sodium: Sodium is related to the balance of fluids in the body, but its deficiency does not cause goiter.
