**Why the Correct Answer is Right**
The abortion stick works by inserting the wire into the cervical os, causing physical obstruction and partial occlusion of the cervical canal. This obstruction prevents the continuation of pregnancy, leading to uterine distension, and eventually, fetal expulsion. The physical trauma and distension can also cause uterine rupture, a life-threatening condition. The mechanism of action is not related to hormonal or pharmacological effects, but rather a mechanical obstruction.
