The correct statement when instructing women about the time when they are most likely to get pregnant (fertile period) is C. Ovulation occurs on or around the 14th day before the next menses is due to begin.
This is because ovulation typically occurs about 14 days before the start of a woman's next menstrual cycle. During ovulation, the ovaries release one or more mature eggs that are viable for fertilization for 24 hours. After the egg is released, it travels down the fallopian tube and is viable for fertilization for 6-12 hours. The sperm, however, can remain viable in the vaginal canal for up to 24 hours. Therefore, a woman is most likely to become pregnant if intercourse occurs around the time of ovulation.
