The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding the Menstrual Cycle**: The menstrual cycle consists of several phases, including the menstrual phase (days 0-5), follicular phase, ovulation, and luteal phase. Ovulation typically occurs around day 14 of a 28-day cycle. 2. **Role of Hormones**: During the follicular phase, the hypothalamus releases Gonadotropin-Releasing Hormone (GnRH), which stimulates the anterior pituitary gland to secrete Follicle Stimulating Hormone (FSH) and Luteinizing Hormone (LH). 3. **Follicle Development**: FSH promotes the maturation of the ovarian follicles, specifically the Graafian follicle, which produces estrogen. As the follicle matures, it releases increasing amounts of estrogen. 4. **LH Surge**: Around day 12-14, the levels of estrogen rise significantly, leading to a surge in LH from the anterior pituitary. This surge is critical for triggering ovulation. 5. **Ovulation**: The surge in LH causes the mature Graafian follicle to release the secondary oocyte, which is the process known as ovulation. 6. **Conclusion**: The hormone responsible for triggering ovulation is Luteinizing Hormone (LH). Therefore, the answer to the question "Ovulation hormone is:" is LH. ---
