Answer

**Step-by-Step Solution:**

1. **Identify the Cells**: Granulosa cells are specialized cells found in the ovarian follicles. They play a crucial role in the development of the oocyte (egg).

2. **Understand the Function of Granulosa Cells**: These cells are responsible for providing nourishment and protection to the developing oocyte. They also play a significant role in hormone production.

3. **Hormones Secreted by Granulosa Cells**: The primary hormones secreted by granulosa cells are:
- **Estrogen**: This hormone is crucial for the growth and development of the ovarian follicles. It stimulates the growth of the follicles and is essential for the menstrual cycle.
- **Progesterone**: Although primarily produced by the corpus luteum after ovulation, some granulosa cells can also contribute to its production.

4. **Conclusion**: Among the hormones secreted by granulosa cells, **Estrogen** is the most significant and well-known hormone associated with these cells.
