• A. Relaxin
• B. Human Chorionic Gonadotropin
• C. Oxytocin
• D. Human Placental Lactogen

Hint:

hCG: Ensures the continuation of pregnancy.
Oxytocin: Induces labor.
Relaxin: Prepares the body for childbirth.
Placental Lactogen: Supports fetal development and metabolism.

Answer 1

The Correct Option is B

Human Chorionic Gonadotropin (hCG) is a hormone secreted by the placenta, playing a crucial role in sustaining pregnancy by supporting the corpus luteum and progesterone production during the early stages.
Relaxin is produced later in pregnancy to help relax the pelvic muscles in preparation for delivery.
Oxytocin triggers uterine contractions during labor.
Human Placental Lactogen aids in fetal growth and metabolism, though it doesn't directly contribute to maintaining pregnancy.
