• B. Progesterone
• C. Testosterone
• D. Thyroxin

Answer 1

The Correct Option is B

Step 1: Understanding the role of hormones Progesterone is a hormone produced by the corpus luteum in the ovary after ovulation. It helps maintain the uterine lining, making it suitable for implantation of a fertilized egg. Step 2: Why other options are incorrect
- Estradiol mainly regulates the menstrual cycle and supports follicular development but does not maintain pregnancy.
- Testosterone is a male hormone and does not play a role in pregnancy.
- Thyroxin regulates metabolism and has no direct role in implantation.
