Plzz answer.
In marking scheme it has been written: oxytocin and prolactin.
What I think: But even oxytocin is released by placenta perhaps.

Dear Student

Hormones secreted by placenta are oestrogen, progesterone, Human chorionic gonadotropin (HCG) and Human placental lactogen (hPL) and Relaxin.

Prolactin and oxytocin are not secreted by placenta.
