The correct answer is: Nearly 99 per cent of the glomerular filtrate is reabsorbed by the renal tubules
The plasma fluid that filters out from glomerular capillaries into Bowman's capsule of nephron is called glomerular filtrate. A comparison of the volume of the filtrate formed per day $(180 \mathrm{~L} /$ day) with that of the urine released $(1.5 \mathrm{~L})$, suggests that nearly 99 per cent of the filtrate has to be reabsorbed by the renal tubules. This process is called reabsorption.
