Answer:
B. about 12 hours
Step-by-step explanation:
Labour is divided into 3 stages. The first stage is the dilation of the cervix, the second stage is the birth of the baby, and the third stage is the delivery of the placenta. For first-time mothers, labour takes around 12 to 14 hours. Women who have undergone childbirth before can expect about 7 hours of labour.
