I'm looking at the question: "The hormone, which stimulates uterus contraction and lets down milk, is:". Based on medical knowledge, the answer is D, Oxytocin. It stimulates uterine contractions during labor and helps with the milk let-down reflex. Prolactin is for milk production, while progesterone relaxes the uterus, and prostaglandins can induce contractions but don’t assist with let-down. I'll include citations for clarity, such as [Gimpl & Fahrenholz, 2001, PMID 11306159] and [Jonas & Johansson, 1995, PMID 7612926].
