The Correct Answer is D
A. Maintaining blood glucose concentration: Incorrect (this is a liver function) -the liver stores glycogen and performs gluconeogenesis to regulate blood glucose.
B. Secretion of bile: Incorrect (this is a liver function) -the liver synthesizes and secretes bile.
C. Formation of urea: Incorrect (this is a liver function) -the liver converts ammonia to urea (urea cycle).
