The graph shows the changing levels of hormones during menstruation and ovulation. what happens to hormone levels during ovulation, and why is this important? a. the hormone levels increase to prepare a woman’s body to receive a fertilized egg.
b. the hormone levels decrease to prepare a woman’s body to receive a fertilized egg.
c. the hormone levels increase, and the next menstrual cycle begins with shedding of the uterine lining.
d. the hormone levels decrease, and the next menstrual cycle begins with shedding of the uterine lining.

The given graph shows the levels of the different hormones during the period of ovulation. During the phase of the ovulation, the hormones level increase. This increase in  the levels of the hormones prepare the uterus for the fertilization of the egg. The uterine line is thickened. This is the phase when the LH  (Luteinizing hormone) surge occurs, which refers to the sudden increase in the levels of LH. Moreover, the levels of FH, estradiol, and progesterone are also increased at different rates during ovulation.

Hence, the correct answer is 'option A - The hormone levels increase to prepare a woman's body to receive fertilized egg'.
