Final Answer :
C
Explanation :
Oxytocin is unique in that its action builds in a positive feedback loop, rather than maintaining an equilibrium. This means that as oxytocin levels increase, the hormone's effects become stronger and more pronounced, leading to even more oxytocin release. This is particularly important in the context of childbirth, where the positive feedback loop helps to promote uterine contractions and ultimately push the baby out.
