Final answer:
Menorrhagia is excessive bleeding during a menstrual period, surpassing the typical amount of blood loss. The option (D) is correct.
Step-by-step explanation:
Menorrhagia is defined as excessive bleeding during a period. Normal menstrual bleeding is about 35 mL, and anything significantly more than this can be considered menorrhagia.
This condition can lead to anemia from the chronic loss of blood and may require medical attention to determine the underlying cause. It is not to be confused with dysmenorrhea, which is pain during menstruation, or amenorrhea, which is the absence of menstrual periods. Therefore, option (D) is correct.
