D. Testosterone

Answer 1

Hint: Iodine is a mineral found in some foods. The body needs iodine to make thyroid hormones. These hormones regulate the body's digestion and various other significant capacities. The body additionally needs thyroid hormones for appropriate bone and mental health during pregnancy and outset.

Complete step by step answer:The thyroid organ is fundamentally made out of follicles and stromal cells. The follicular cells are answerable for the creation of thyroxine (T4) and triiodothyronine (T3) hormones. Presently, iodine is answerable for the union of these thyroid hormones and furthermore for the typical pace of creation of thyroid hormone. Now, iodine is responsible for the synthesis of these thyroid hormones and also for the normal rate of production of thyroid hormone. So, deficiency of iodine in our diet results in hypothyroidism which leads to an increase in the size of the thyroid gland. This growth of the thyroid gland is generally called a goitre. It(goitre) can be caused due to the following:
Decreased intake in our diet.
Increased demand during puberty, pregnancy
and lactation. Intake of goitrogens i.e. cabbage.
It must be known that hypothyroidism in pregnant women can cause defective development and maturation of the growing baby and in adult women, it may cause baby and in adult women, it may cause the menstrual cycle to become irregular. Consequently, to forestall these conditions, iodine has been added to our salts and that is the reason iodised salt is prompted. The suggested day by day admission of iodine is 150Mg/day.
Thus, the answer is option B: Thyroxine.

Note:Thyroid gland is known as the largest gland of the body. Thy thyroid hormones are necessary as they control the basal metabolic rate of cell respiration. Iodine is needed by the thyroid gland for the production of thyroxine hormone.
