Final answer:
The correct answer is B- 8-12%, as women require a higher body fat percentage for normal reproductive function, and dropping below this can lead to amenorrhea and loss of body mass.
Step-by-step explanation:
The correct answer to the question is B- 8-12%. Women may experience amenorrhea, which is the absence of menstruation, and loss of body mass if their percentage of body fat falls below the essential level needed for the normal functioning of the reproductive system. A certain amount of body fat is important for women not only for overall health but also for reproductive health.
When body fat percentage drops too low, women can experience hormonal imbalances that affect their menstrual cycle. The essential fat percentage range for women is significantly higher than that for men, in part to support fertility and reproductive health. Thus, when body fat falls below 8-12%, women can face reproductive issues such as amenorrhea and may also show signs of infertility or other hormonal imbalances.
