Choose the correct answer from the options given below:

A-IV, B-III, C-II, D-I

The correct answer is option 2. A-IV, B-III, C-II, D-I.

Let us look at the functions of the given hormones:

A. Insulin: Insulin is a hormone produced by the pancreas, specifically by the beta cells in the islets of Langerhans. Its primary function is to regulate blood glucose levels. Insulin facilitates the uptake of glucose by cells from the bloodstream and promotes the conversion of glucose into glycogen for storage in the liver and muscles. Thus, insulin helps lower blood glucose levels.

B. Thyroxine: Thyroxine, also known as T4, is a hormone produced by the thyroid gland. It plays a crucial role in regulating metabolism, growth, and development in the body. Thyroxine affects almost every cell in the body and influences processes such as energy production, heart rate, body temperature, and digestion.

C. Testosterone: Testosterone is the primary male sex hormone (androgen) produced mainly in the testes. It plays a key role in the development of male reproductive tissues such as the testes and prostate, as well as in the development of secondary sexual characteristics such as increased muscle mass, facial and body hair growth, and deepening of the voice.

D. Estradiol: Estradiol is the primary female sex hormone (estrogen) produced mainly in the ovaries. It plays a central role in the menstrual cycle and reproductive function. Estradiol is involved in the development of female secondary sexual characteristics such as breast development and widening of the hips. It also plays roles in bone health, mood regulation, and cardiovascular health.

So, the correct match is: A-IV, B-III, C-II, D-I
