Which element is needed by the body to make thyroxine?
Answer and explanation
Correct answer: Iodine
The thyroid gland requires iodine to synthesize thyroxine, a hormone involved in regulating metabolism, growth, and development. The body obtains iodine from dietary sources, and inadequate iodine can reduce thyroxine production and cause enlargement of the thyroid gland, called goitre. Therefore option B is correct. Iron, calcium, and sodium are essential nutrients for other functions but are not the specific raw material for thyroxine.
