B.
The menstrual fluid can easily clot
During normal menstruation, approximately 40 mL of blood and an additional 35 mL of serous fluid are lost. The menstrual fluid is normally non-clotting because a fibrinolysin is released along with the necrotic endometrial material.
The cause of menopause is burning out of the ovaries. At about age 45 only a few primordial follicles remain to be stimulated by FSH and LH. The oestrogen production falls below a critical value and the gonadotropic hormones (FSH and LH) are produced regularly from the pituitary so, a there level increase in body.
