C Correct answer
Explanation

Stores of readily available glucose to supply the tissues with an oxidizable energy source are found principally in the liver, as glycogen. 

Glycogen is a polymer of glucose residues, linked by (1,4)- and -(1,6)-glycosidic bonds. A second major source of stored glucose is the glycogen of skeletal muscle. 
However, muscle glycogen is not generally available to other tissues, because muscle lacks the enzyme glucose-6-phosphatase. 
Glucose-6-phosphatase enzyme catalyses the conversion of glucose-6-phosphate to glucose. So, Blood glucose level is not dependent upon muscle glycogen.
