Which statement correctly describes effacement in labor?

Explanation:
Effacement is about thinning of the cervix. As labor progresses, the cervix shortens and becomes thinner, described as a percentage from 0% (not thinned) to 100% (fully thinned). Dilation, by contrast, measures how open the cervix is, from 0 cm to about 10 cm. So the statement that effacement refers to thinning of the cervix is the correct description. The others mix up thinning with opening: dilation describes opening in centimeters, not thinning.
