HPL otherwise known as HUMAN CHORIONIC SOMATO MAMMOTROPIN helps in differentiation of mammary gland till the last month of pregnancy,oxytocin's effect will be felt only after the delivery when the levels of progesterone n estrogen decrease drastically.

C

I'd bet my money on C. they mentioned Oxytocin as a trap because it doesnt work till the baby start feeding.

Kind regards,

HPL is only present during pregnancy with maternal serum levels rising in relation to the growth of the fetus and placenta. Maximum levels are reached near term, typically to 5–7 mg/ml. Higher levels are noted in patients with multiple gestation. Little HPL enters the fetal circulation.

Human Placental Lactogen (HPL) is the same of HUman Chorionic somatomammotropin.
