The correct Answer is:
To solve the question, we need to evaluate each statement regarding oxytocin and determine which ones are true. ### Step-by-Step Solution: 1. **Evaluate Statement i**: - "During parturition, oxytocin induces intense contractions in the uterus." - **Analysis**: This statement is true. Oxytocin is known to stimulate uterine contractions during childbirth (parturition). 2. **Evaluate Statement ii**: - "After parturition, oxytocin stimulates milk ejection." - **Analysis**: This statement is also true. After childbirth, oxytocin plays a crucial role in the milk ejection reflex during breastfeeding. 3. **Evaluate Statement iii**: - "The labour pain during childbirth is due to oxytocin." - **Analysis**: This statement is true as well. Oxytocin is involved in inducing labor pain by stimulating contractions of the uterus. 4. **Evaluate Statement iv**: - "Oxytocin is secreted from placenta and ovary." - **Analysis**: This statement is false. Oxytocin is produced in the hypothalamus and released by the posterior pituitary gland, not directly from the placenta or ovary. ### Conclusion: - The true statements are i, ii, and iii. - The false statement is iv. ### Final Answer: The correct option with all true statements is the one that includes statements i, ii, and iii. ---
