Final answer:
Breech presentation poses challenges in vaginal birth, occiput anterior vertex is the easiest, and Caesarean section may be necessary for complications.
Explanation:
Breech presentation, where the baby is oriented buttocks down, is the most complicated in vaginal birth. In this presentation, the baby is not positioned head first, leading to increased risks during delivery.
Vaginal birth is associated with stretching of the vaginal canal, cervix, and perineum. The occiput anterior vertex presentation, with the baby's head facing the maternal spinal cord, is the most common and easiest for vaginal birth.
Complications during vaginal birth may require Caesarean section delivery, especially in cases of breech presentation to ensure the safety of both the baby and the mother.
