B. 2)Ovary
C. 3)Corpus luteum
D. 4)Uterine epithelium

Answer

To answer the question "The female hormone inhibin is secreted by," we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Hormone Inhibin**:
- Inhibin is a proteinaceous hormone that plays a role in regulating the reproductive system, specifically by reducing the secretion of Follicle Stimulating Hormone (FSH).

2. **Identify the Source of Inhibin in Females**:
- In females, inhibin is secreted primarily by the granulosa cells of the ovarian follicles and the corpus luteum after ovulation.

3. **Evaluate the Options**:
- **Option 1: Zona Pellucida** - This is a glycoprotein layer surrounding the oocyte and does not secrete hormones.
- **Option 2: Ovary** - While the ovary contains cells that produce inhibin, it is not the direct source.
- **Option 3: Corpus Luteum** - This structure is formed from the ovarian follicle after ovulation and is a known source of inhibin.
- **Option 4: Uterine Epithelium** - This does not secrete inhibin.

4. **Select the Correct Answer**:
- Based on the information, the correct answer is **Option 3: Corpus Luteum**.

### Final Answer:
The female hormone inhibin is secreted by the **Corpus Luteum**.
