Menopause is the cessation of the monthly cycle wherein ovaries do not respond to gonadotropic hormones produced by the anterior pituitary and do not secrete oestrogens and progesterone. It marks the end of a reproductive phase of the human female. Deposition of subcutaneous fat, the presence of pubic hair and development of mammary glands are secondary sexual characters in human females. The correct answer is A.

• Menstruation is a woman's monthly bleeding. It occurs so as to shed the lining of the uterus or womb. 
• In the menstrual cycle, the uterus gets prepared for implantation and the endometrium builds up. 
• After ovulation, if the egg released after fertilization, does not get implanted in the uterus, it leads to shedding off this endometrium and its lining and mucus and this is called menstruation. 

The level of progesterone hormone decreases after the regression of corpus luteum, causes the uterus to shed its lining and egg in a process termed as menstruation. 

• Menstruation is a woman's monthly bleeding. It occurs so as to shed the lining of the uterus or womb. In the menstrual cycle, the uterus gets prepared for implantation and the endometrium builds up.
•  After ovulation, if the released egg does not get implanted in the uterus, it leads to shedding off the endometrium and its lining and this is called menstruation and it generally lasts for 3-4 days.

• Menstruation is a woman's monthly bleeding. When the egg is released by the ovary, the body prepares for fertilization but building up the uterine layer and other hormonal changes. 
• However, if the egg is not fertilized, the body sheds this lining of the uterus and mucus and this is called menstrual blood and it passes from the uterus through the cervix and passes out the body through the vagina.

The mature egg is released from the ovary and pushed down the fallopian tube for it to fertilize. If no fertilization takes place, the egg degenerates and is shed from the body along with the uterine lining as well as the blood, which happens during the menstruation.
Thus, the correct answer is option B.

Once a girl starts menstruation, her body needs more iron to make up the amount of iron they lose in their menstrual cycle. During menstruation, blood flows out from the body after a fixed interval. As we know haemoglobin is composed of a protein called globulin, four heme groups, each associated with an iron atom. In the absence of iron the person becomes anemic. So, avoid this condition in females, it is necessary to take more iron in females.
