Final answer:
A Pfannenstiel incision would require cutting through Scarpa's fascia, as it is a transverse incision made in the lower anterior abdominal wall.
Step-by-step explanation:
The incision that would require cutting through Scarpa's fascia is the C. Pfannenstiel incision. Scarpa's fascia is a layer of deep fascia in the lower anterior abdominal wall. A Pfannenstiel incision, often used in gynecologic surgeries and cesarean sections, involves a transverse cut just above the pubic symphysis and would necessitate cutting through this fascia.
