The correct Answer is:
To answer the question regarding the sex hormone that controls the development and maintenance of pregnancy, we can follow these steps: ### Step-by-Step Solution: 1. **Identify the Options**: The question provides four options: - Option 1: Cortisone - Option 2: Thyroxine - Option 3: Progesterone - Option 4: Esterone 2. **Understand the Role of Hormones in Pregnancy**: - Hormones are crucial for regulating various physiological processes, including the menstrual cycle and pregnancy. - During pregnancy, specific hormones are responsible for maintaining the pregnancy and supporting fetal development. 3. **Evaluate Each Option**: - **Cortisone**: This is a steroid hormone involved in stress response and metabolism but does not play a direct role in pregnancy maintenance. - **Thyroxine**: This hormone is produced by the thyroid gland and regulates metabolism but is not primarily involved in pregnancy maintenance. - **Progesterone**: This hormone is produced in the ovaries and later in the placenta during pregnancy. It plays a significant role in preparing the body for conception and maintaining pregnancy. - **Esterone**: This is an estrogen hormone but does not specifically control pregnancy maintenance. 4. **Confirm the Role of Progesterone**: - Progesterone prepares the uterus for implantation of the fertilized egg and helps maintain the uterine lining throughout pregnancy. - It regulates the menstrual cycle and prevents ovulation during pregnancy. - Progesterone levels remain elevated during pregnancy, which is crucial for the development of the fetus. 5. **Conclusion**: Based on the evaluation of the options and understanding the role of progesterone, we conclude that the sex hormone which controls the development and maintenance of pregnancy is **Progesterone** (Option 3). ### Final Answer: The sex hormone which controls the development and maintenance of pregnancy is **Progesterone**. ---
