Options

A. oestrogen
B. oxytocin
C. prostaglandins
D. All of these

Answer

**Step-by-Step Solution:**

1. **Understanding Parturition**: Parturition refers to the process of childbirth, where the developed fetus is expelled from the uterus. This is commonly known as delivery.

2. **Identifying Relevant Hormones**: The question asks for the hormone responsible for triggering parturition. The options provided are:
- Option 1: Oestrogen
- Option 2: Oxytocin
- Option 3: Prostaglandins
- Option 4: All of these

3. **Analyzing Each Option**:
- **Oestrogen**: This hormone plays a role in the proliferation of the uterine walls but does not directly induce parturition.
- **Oxytocin**: This hormone is crucial for parturition as it stimulates uterine contractions during labor.
- **Prostaglandins**: While they are involved in the process of labor, they do not directly cause parturition in the same way oxytocin does.
- **All of these**: Since not all the listed hormones are responsible for inducing parturition, this option is incorrect.

4. **Conclusion**: After analyzing the options, it is clear that the hormone that primarily causes parturition is **Oxytocin**.

5. **Final Answer**: The hormone which causes parturition is **Oxytocin**.
