Hint: There are certain hormones that are needed for male and female organisms to express their sexual characteristics, differently from the opposite sex. These are mostly steroid hormones that interact with steroid hormone receptors. They introduce characteristics like facial hair, body mass, etc in males and enlargement of breasts, widening of hips, etc in the case of females.

Complete step by step answer:
Estradiol is a major female sex hormone that regulates the estrous and menstrual cycles in females. The growth hormone is a peptide hormone that stimulates growth in organisms. Testosterone is the male sex hormone and also an anabolic steroid. It develops the reproductive tissues and promotes sexual growth in males. Adrenaline is a hormone produced by the adrenal glands and acts as a neurotransmitter.
So, the correct answer is, 'Testosterone.'

Additional Information: Testosterone is the prime male sex hormone. It is also an anabolic steroid. Although it is the primary male sex hormone, it is also secreted by ovaries in females. In males, it is secreted by testes. It is also secreted by the adrenal gland in both sexes.
This is the main hormone that induces secondary male sexual characteristics. It binds with a special androgen receptor and develops characteristics such as the growth of facial hair and increased body mass. Lack of testosterone can affect the male b, body. It causes a lack of facial hair, reduced body mass, lack of body hair, lack of sex drive, etc.

Note: Testosterone is secreted in very less amounts in females. It helps in the growth, maintenance, and repair of female reproductive tissues, bone mass, and human behavior. But an increase in testosterone in females can cause the development of male characteristics in a female body. Therefore, in spite of being secreted in both sexes, it is mainly considered a male sex hormone.
