The correct option is D
Urea

Urine formation takes place in three steps, i.e., filteration, reabsorption and secretion. During reabsorption, all the required components are reabsorbed. Water, amino acids, glucose and salts are usually reabsorbed. Urea is not required by the body. So, it is not reabsorbed.
