Answer: L5

Explanation: Disc herniation refers to the process in which disc material is locally displaced beyond the intervertebral disc space limits.

Disk herniation posterolaterally brings about ipsilateral nerve root compression, as it exceeds the dural sac.

However, a posterolateral disc herniation of the L4 to L5 intervertebral disk results in of the L5 root compression.
