The anatomic landmark that can be used to identify the left medial segment separate from the right anterior segment of the liver is the middle hepatic vein. Option D is correct.

The liver is divided into eight segments based on the distribution of its blood supply. The division is based on the location of the portal triads, which consist of the hepatic artery, hepatic portal vein, and bile duct. The middle hepatic vein divides the liver into right and left halves. The left medial segment is located to the left of the middle hepatic vein and includes segments IVa and IVb, while the right anterior segment includes segments V and VIII.
