D. Both (A) and (B)

Answer

To solve the question "Which of the following is/are used to induce parturition?", we will analyze each option provided.

### Step-by-Step Solution:

1. **Understanding Parturition**:
- Parturition refers to the process of childbirth or the delivery of the fetus. It involves a series of physiological changes and contractions in the uterus.

2. **Identifying the Options**:
- The options given are:
- A) Oxytocin
- B) Pitocin
- C) Astrogen
- D) Both A and B

3. **Analyzing Option A - Oxytocin**:
- Oxytocin is a hormone produced by the posterior pituitary gland. It plays a crucial role in stimulating uterine contractions during labor, making it essential for parturition.

4. **Analyzing Option B - Pitocin**:
- Pitocin is a synthetic form of oxytocin. It is administered to induce labor and enhance uterine contractions, thus also contributing to the process of parturition.

5. **Analyzing Option C - Astrogen**:
- Astrogen (likely a typographical error for "Estrogen") is a hormone that regulates female secondary sexual characteristics and the menstrual cycle. While it plays a role in reproductive health, it is not primarily responsible for inducing parturition.

6. **Conclusion**:
- Based on the analysis, both Oxytocin and Pitocin are used to induce parturition, while Astrogen does not play a direct role in this process. Therefore, the correct answer is **D) Both A and B**.

### Final Answer:
**D) Both A and B**
