Answer 1

Answer: (B)

blood sugar is lower than the renal threshold for glucose

Diabetes Mellitus is due to deficiency or absence of insulin or interference in insulin activity. Prolonged hyperglycemia leads to this complex disorder called diabetes mellitus. Diabetes mellitus causes the following effects :

(A) Raised blood glucose level.

(B) Glycosuria and Polyuria- this causes electrolyte imbalance and excretion of urine of high specific gravity. Polyuria leads to hypovolaemia, extreme thirst, and polydipsia.

(C) Weight loss

So the correct answer is blood sugar is lower than the renal threshold for glucose.
