Step-by-step explanation:
The term that refers to the herniation of the liver is a) hepatocele. A hepatocele is a rare condition where part of the liver protrudes through a hole or a weak point in the abdominal wall. It's different from hepatic encephalopathy, which is a reversible neuropsychiatric abnormality associated with liver failure, and surgical procedures such as hepatopexy (fixation of the liver) or nephropexy (fixation of a kidney) do not refer to liver herniation. Moreover, nephrocele refers to herniation involving the kidney, not the liver.
