D) Testis- testosterone

Answer 1

Leydig cells are also called the interstitial cells. Which is located adjacent to the seminiferous tubules in testicle. It produces testosterone in the presence of luteinizing hormone. Leydig cells are important for male stem production. Males reproduction hormone is the responsible for the growth and maintenance of the cell and also for the development of secondary sex characteristics.

Option A: Ovary produces the sexual hormones like estrogen and progesterone. Estrogen produces three important things called estradiol, estrone, and estriol. This is used for good health in puberty.
Option B: Important function of the liver is to produce cholesterol. Liver is called the nutritional powerhouse. Liver not only exports the cholesterol but also removes the cholesterol in the human body.
Option C: pancreas produces the glucagon which is called the peptide hormone. It increases the concentration of glucose and fatty acids in the bloodstream.
Option D: Testis produces the male hormones. Male hormones are testosterone and androgen. Testosterone is the primary sex hormone.

So, the correct answer is “Option D”.

Note:
The high level of testosterone production may cause sex drive, bone mass, fat distribution, muscle mass and strength to the human body. It also produces red blood cells and sperm. More testosterone production leads to more aggressive, less sleep, and oilskins. If the production is less than it may lead to low sex drive and reduces bone mass. It will also reduce hair growth, voice and appearance. Average level of testosterone production in the human body is $60\%$.
