Explanation:
Positive feedback is a process taking place in the organisms during which the output or the end product of the process causes the process or action o occur continuously or it stimulates the process to go on. A loop of action is formed during the positive feedback mechanism.
During labour, the production of oxytocin hormone plays an important role in the uterine contraction which allows the birth of the baby.
The production of oxytocin during labour is considered positive feedback as the oxytocin-induced contraction and the contraction causes more oxytocin to be released until the baby is born.
Thus, Positive feedback is the correct answer.
