Answer 1

The correct option is: B. Iliohypogastric nerve

Step-by-step explanation:

Iliohypogastric nerve is a type of mixed nerve that arises from lumbar plexus of the lumbar region and supplies sensation or innervates the skin over the internal oblique and the transverse abdominal muscles and the gluteal, inguinal, and pubical regions of the human body. Therefore, the iliohypogastric nerve is also known as iliopubic nerve.

Therefore, the numbness of skin over the pubic region is due to the injured Iliohypogastric nerve.
