Quizplus · Accepted Answer

The onset of menarche (the first occurrence of menstruation) typically occurs between the ages of 11 and 14. Although it can occur as early as age 8 or as late as age 16, the majority of girls experience their first period between the ages of 11 and 14. Option A is incorrect because while it is possible for a girl to start menstruating at age 8, it is not typical. Option B is incorrect because while some girls may start later (up to age 16), this is not the norm. Option D is incorrect because most girls will have already started menstruating by age 18.
