B. Oxytocin
C. ACTH
D. Growth hormone

Answer

To determine which of the following is not a hormone of the anterior pituitary, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Function of the Anterior Pituitary**: The anterior pituitary gland is responsible for producing and secreting several important hormones that regulate various bodily functions.

2. **List the Hormones of the Anterior Pituitary**: The key hormones released from the anterior pituitary include:
- Follicle-Stimulating Hormone (FSH)
- Luteinizing Hormone (LH)
- Prolactin (PRL)
- Growth Hormone (GH)
- Thyroid-Stimulating Hormone (TSH)
- Adrenocorticotropic Hormone (ACTH)

3. **Identify the Options Given**: The question provides several options, one of which is not a hormone produced by the anterior pituitary.

4. **Analyze Each Option**:
- **Option 1: Prolactin (PRL)** - This is a hormone produced by the anterior pituitary.
- **Option 2: Oxytocin** - This hormone is produced in the hypothalamus and released by the posterior pituitary, making it not a hormone of the anterior pituitary.
- **Option 3: Adrenocorticotropic Hormone (ACTH)** - This is a hormone produced by the anterior pituitary.

5. **Conclusion**: Since Oxytocin is the only hormone listed that is not produced by the anterior pituitary, it is the correct answer.

### Final Answer:
**Oxytocin** is not a hormone of the anterior pituitary.
