Final answer:
Cirrhosis is the disease characterized by elevated GGT and ALT levels, with ALT > AST.
Step-by-step explanation:
The disease characterized by elevated GGT (gamma-glutamyltransferase) and ALT (alanine aminotransferase) levels, with ALT > AST (aspartate aminotransferase), is cirrhosis (option b).
In cirrhosis, there is chronic liver failure, which can be caused by various factors such as excessive alcohol intake, hepatitis B or C, autoimmune diseases, hereditary conditions, and metabolic causes like iron or copper overload or non-alcoholic fatty liver disease.
GGT is a liver enzyme that can be elevated with liver dysfunction, and ALT is a liver enzyme that is more specific to liver damage. In cirrhosis, ALT levels are typically higher than AST levels.
