Verified by Experts

The correct Answer is:
A
A patient of diabetes mellitus is unable to produce or fail to utilize insulin hormone. Thus, he is unable to store glucose in the form of glycogen. Hence, he started to excrete glucose in the urine. A patient is kept in carbohydrate free diet yet he excretes glucose in urine because a high level of glucose not only depends on dictary carbohydrates but also on glycogenolysis (degradation of glycogen in the liver) and gluconeogenesis (breakdown of fats into glucose in adipose tissues and conversion of muscle lactate into glucose via Cori cycle).
