Additional information
> Anti-Mullerian hormone (AMH), also known as Mullerian-inhibiting hormone (MIH), is a glycoprotein hormone structurally related to inhibin and activin from the transforming growth factor-beta superficially, whose key role is in growth dedifferentiation.
> Progesterone is mainly secreted by the corpus luteum in the ovary during the second half of the menstrual cycle and plays an important role in maintaining the early stages of pregnancy.
> Progesterone prepared the body from the time of fertilization of an egg.
> If the egg is not fertilized, the corpus luteum breaks down, the production of progesterone falls and a new menstrual cycle begins. Hence, progesterone is called the anti-abortion hormone.
> Progesterone is sometimes called the “hormone of pregnancy “ and it has many roles relating to the development of the fetus.

So, the correct answer is Progesterone.

Note: Relaxin is a protein hormone secreted by the corpus luteum in the ovary. It softens the womb neck and relaxes the pubic joint of the pelvis to ease childbirth. Oxytocin is a peptide hormone that is used to start labor and Oestrogen is the primary female sex hormone.
