In general, the liver:.
a) does not utilize glucose under starvation/low-energy conditions.
b) acts as a glucose buffer for the rest of the body.
c) is a producer of glucose for the body under low-energy conditions.
d) all of the above
e) none of the above

ALL of the above-D

Explanation:

The liver is an organ involved in metabolism of  carbohydrate, proteins and fats  in the body. In case of low  blood glucose, Glucagon,(in the pancreas) hormone, cortisol, growth hormones epinephrine,  stimulated the conversion of glycogen stored in the muscle cells to glucose which  boost the blood glucose levels., for distribution to all body cells.

In case of low energy conditions, the liver ensures production of glucose from non carbohydrate sources  e,g gluconeogensis so that glucose could be made available for  body organs survival. For example during starvation, fats and proteins are converted to glucose by the liver to conserve  and maintain constant body glucose levels.
