Hint: Ovary is a ductless reproductive gland in which female reproductive cells are produced. Females have a pair of ovaries, which are held by a membrane beside the uterus on either side of the lower abdomen. The ovaries are needed for reproduction because they are responsible for the production of female reproductive cells or ova.

Complete answer:
The ovaries are two small organs, about the size of your thumb, which are located in the female pelvis. They are attached to the uterus, one on each side, close to the opening of the fallopian tube. The ovary produces a female gamete cell called an oocyte. In non-medical terminology, the oocyte is called the "egg". The ovaries are full of follicles. Follicles are fluid-filled structures in which the oocyte (also known as an egg) develops to maturity. Current information suggests that females are born with their entire life supply of gametes. Upon formation, the average female ovary produces around 1-2 million oocytes (eggs). Females are not able to make new eggs, and there is a persistent decrease in the total number of eggs every month.
Large supplies of eggs inside each ovary are either immature or primary and must undergo growth and maturation every month. The eggs are deposited in the follicles of the ovary. In the lifetime of a woman, a large number of follicles and oocytes will be recruited to begin the process of growth and maturation. However, the vast number will not reach full maturity. Most of them would die off in a process called atresia. As a result, only around 300-500 of these eggs can mature during a woman's life.
A human female has approximately 4,000,000 follicles, which are potential eggs. Out of these, only about 480 eggs have been released during the reproductive years. During the menstrual cycle, one egg is matured and released from the ovaries each cycle. If the left ovary releases a potential egg in the first month, the right ovary releases a potential egg in the next month. Thus in the absence of embryo implantation, 6 eggs are released per ovary per year.
Thus, the answer is option B: 6

Note: Ovarian diseases are disorders that affect young women's reproductive systems and general health. These may be categorized as endocrine disorders or reproductive system disorders. If the egg is not released from the follicle in the ovaries, the ovarian cyst can develop.
