A 52-year-old man comes to the physician because a ...
Sensation from the anterior surface of the scrotum
I think you're right, FA2019 pp444 even states that sensory to the scrotum is via the Genitofemoral nerve
Ilioingual covers part of the medial thigh, base of penis and anterior scrotum
Posterior scrotal nerves are a branch of pudendal and cover said area
Doral nerves cover the dorsum of the penis which are also from the pudendal
I thought it was the Genitofemoral nerve because the genital branch supplies the cremaster and scrotal skin, but I looked it up and: The genital branch passes through the *deep inguinal ring* and enters the inguinal canal; also, Ilioinguinal wraps around the spermatic cord just like the question stem says.
Adding to this...
The Q is describing the GENIOFEMORAL nerve, which runs EXTERNAL TO of spermatic cord at the superficial inguinal ring
This Q is NOT referring to ilioinguinal nerve, which exits THROUGH the superficial inguinal canal
