Answer 1

Hint: The excretory organs are also called urinal organs. The reproductive organs are genital organs that are already mentioned in the question.

Complete answer: The excretory organs are also called urinary organs as the organs help in the production of urine. The organs include kidney, urinary bladder, renal duct etc.
The reproductive organs are also called genital organs. This includes testis, urethra, sperm ducts, and penis in case of males, ovary, uterus, fallopian tubes, and vagina in case of females.
So, the renal organs for excretion and the genital organs for reproduction are commonly known as urogenital organs.

Additional information: During embryonic development the urogenital tract is developed simultaneously. Then they separate in the adult stages of life.
1. In the case of males, the urinary opening and the genital opening are the same but in the case of females the urinary opening and genital opening are different from the embryonic condition.
2. This Urogenital system is also known as the genitourinary system.
3. The organs of the excretory system helps in the production of urine and the organs of the reproductive system helps in the production of sperms and eggs in males and females respectively.
4. The female reproductive system also controls the menstrual cycle and produces hormones like oestrogen, progesterone etc.
5. The male reproductive organs only produce a hormone called testosterone.

So, option C. Urogenital organs are the correct answer.

Note: The structural and functional unit of the kidney is nephron, which helps in the production of urine.
