Which statement best describes Stage I of labor?

Explanation:
Stage I is all about the cervix opening from the start of contractions up to full dilation, culminating at 10 cm. During this stage the cervix goes through three phases—latent (early dilation), active (faster dilation), and transition (the strongest contractions as dilation nears completion). This window from the onset of contractions to 10 cm dilation best describes Stage I. In contrast, Stage II spans from full dilation to the baby’s birth, Stage III from birth to placental delivery, and contractions starting in the first trimester aren’t how labor stages are defined.
