C. Ovaries and uterus
D. Ovaries and anterior pitutary.

Answer

**Step-by-Step Solution:**

1. **Identify the Hormones Involved in the Menstrual Cycle:**
- The key hormones involved in the menstrual cycle are Luteinizing Hormone (LH), Follicle Stimulating Hormone (FSH), Estrogen, and Progesterone.

2. **Determine the Source of Each Hormone:**
- **LH and FSH:** These hormones are produced by the anterior pituitary gland.
- **Estrogen and Progesterone:** These hormones are produced by the ovaries, specifically by the ovarian follicles and the corpus luteum.

3. **Analyze the Options Provided:**
- **Option A:** Ovaries only - This is incorrect because it does not account for LH and FSH.
- **Option B:** Uterus only - This is incorrect as the uterus does not produce these hormones.
- **Option C:** Ovaries and uterus - This is incorrect because the uterus does not produce the hormones involved in the menstrual cycle.
- **Option D:** Ovaries and anterior pituitary - This is correct as it includes both the source of estrogen and progesterone (ovaries) and the source of LH and FSH (anterior pituitary).

4. **Conclusion:**
- The correct answer is **Option D: Ovaries and anterior pituitary**.
