The Correct Answer is A
The sacral roots have a long way to travel in the vertebral canal; the spinal Nn & their split into dorsal & ventral rami actually occur in the vertebral canal. The dura mater & cerebrospinal fluid end at about S2. Below in the epidural space is where saddle block (epidural) injections are given for women in labor; there’s no worry of anesthetizing the CNS & labor pain is decreased, but leaves enough feeling for the woman to know when to push.
Saddle block or epidural block anesthetize area of buttocks, perineum & inner thigh (area that literally sits on saddle)
