Answer 1

Hint Hormones play a vital role in the growth, development, and metabolism of specific cells and organs in our body. Sex hormones are reproductive hormones. While the gonadotrophin hormones are produced by different tissue and assist in gonadic regulation.

Complete Step-by-step answer:
Sex hormones are also known as steroid hormones. Estrogen, progesterone, and testosterone are examples of steroid hormones.
Estrogen regulates the menstrual cycle, develop female features, and maintains pregnancy. When the egg is fertilized progesterone prepares the body for pregnancy. Both estrogen and progesterone are produced in the ovary.
Testosterone hormones produce both in the ovary and testes. Testosterone helps in the development of male features and helps in body density both male and female.
Gonadotrophin hormones play an important role in reproductive health. Follicle-stimulating hormone (F SH), Luteinizing hormone (LH), and Human chorionic gonadotrophin are gonadotropin hormones. These hormones assist gonads to mature and function.  In men, these hormones cause the testicles to make testosterone. In women, they cause the ovaries to make estrogen and progesterone. 
The follicle-stimulating hormone regulates the production of sperm and eggs while the luteinizing hormone regulates estrogen and testosterone production and ovulation.
Gonadotrophin hormone level is low in children but rises during puberty. When the sex hormone level is high our body makes less gonadotrophic releasing hormone and vice versa. But during the time of female ovulation body make more gonadotrophic releasing hormone.
Hence the correct answer is option D.

Note: Hormonal imbalance can occur in case of low and high secretion of sex hormones. It leads to menopause, PCOS, Ovarian tumour, miscarriage, premature birth, the problem with ovulation, low sperm count, etc
