Hint:Ovulation occurs on stimulation with some specific hormone. This process occurs every month. There is a release of only one egg after the rupture of the mature Graafian follicle.

Complete answer:Ovulation is the process of releasing the matured egg or ovum from the mature follicle in the ovary in females. It can be divided into 3 phases:
1. The pre-ovulatory or follicular phase: A layer of cells around the ovum becomes more like mucus, and expand. The uterus lining begins to thicken.
2. The ovulatory phase: Enzymes are secreted and form a hole, or stigma. The ovum and its network of cells use the stigma to move into the fallopian tube. This is the period of fertility and usually lasts from 24 to 48 hours.
3. The post-ovulatory or luteal phase: LH is secreted. A fertilized egg will be implanted into the womb, while an unfertilized egg slowly stops producing hormones and dissolves within 24 hours.
The follicle-stimulating hormone (FSH) stimulates the ovarian follicle causes an egg to grow. It also triggers the production of estrogen in the follicle. The rise in estrogen gives a signal to your pituitary gland to stop producing FSH and to start making more luteinizing hormones (LH). The shift to LH causes the egg to be released from the ovary, a process called ovulation.
Thus, option B is the correct answer i.e.,Luteinizing hormone.

Additional information:
Follicle-stimulating hormone and luteinizing hormone are both synthesized by the pituitary gland of the human body (a small gland located underneath the brain). Both of these hormones play an important role in sexual development and functioning of women's ovaries and men's testes whereas testosterone is the most important sex hormone synthesized in men, which causes puberty, muscle mass growth, and strengthen the bones and muscles, increase bone density and controls facial hair growth.

Note:The ovulation process is defined by a period of elevated hormones during the menstrual cycle. However, a significantly low amount of testosterone is produced in females. It affects menstruation, fertility, RBC production, and bone and tissue mass.
