Answer 1

The correct option is C

Testosterone from the testes and Oestrogen from ovaries.

The correct option is C.

Explanation of the correct option:

1. Puberty is the stage in life when a person goes through many changes.
2. The significant change is the development of the secondary sexual characters.
3. In the case of females, estrogen released from the ovary is responsible for developing female secondary sexual characteristics, and testosterone released from the testes in the male is responsible for producing male secondary sexual characters.

Explanations for incorrect options:

Option A:

• Oestrogen does not release from the testes, and testosterone does not release from the ovary, so this option is incorrect.

Option B:

• Estrogen does not release from the adrenal gland. The adrenal gland releases the adrenalin, and testosterone does not release from the pituitary gland.

Option D:

• Testosterone does not release from the thyroid gland, and estrogen does not release from the pituitary gland, so this option is incorrect.

Final Answer: the dramatic changes in the body features associated with puberty are mainly due to the release of testosterone from the testes and oestrogen from the ovaries.
