Answer 1

Answer: (A)

(iii), (iv)

Iodine is necessary for the thyroid gland to make the thyroxine hormone.

Secondary sexual characters appear in adolescents due to the release of sex hormones - testosterone (male) and oestrogen (female).

The adrenal gland produces adrenaline hormone.

The hypothalamus releases hormone that stimulates the pituitary gland to release growth hormones.

So, statements (iii) and (iv) are incorrect.

Hence, the correct answer is option A.
