Verified by Experts

The correct Answer is:
A
Renal threshold of a substance is its highest concentration in the blood upto which it is totally reabsorbed from the glomerular filtrate. Renal threshold of glucose is about 180 mg/ 10 mL. Glucose is reabsorbed and does not appear in the urine as long as its blood level does not exceed 180 mg/ 100 mL.
