• A. Days 1 - 6
• B. Days 7 - 14
• C. Days 15 - 22
• D. Days 23 - 28

Answer: (B)

The typical duration of the follicular phase in the menstrual cycle is commonly recognized as taking place from around day 1 to day 14. This phase begins on the first day of menstruation and continues until ovulation occurs, which typically happens around the middle of the cycle. During this phase, the follicles in the ovaries mature under the influence of follicle-stimulating hormone (FSH), leading to the development of a dominant follicle that will eventually release an egg.

The recognized timeline helps to understand the cyclical nature of the menstrual process, allowing for better tracking of ovulation and fertility. Each woman’s cycle can vary, but the 14-day average for the follicular phase aligns tightly with the typical range of menstrual cycle lengths. It's important to note that the other options represent different phases of the menstrual cycle: the luteal phase and menstrual bleeding or are simply not aligned with standard cycle markers.
