None of the above

Detailed explanation-1: -Tubular reabsorption is the process that moves solutes and water out of the filtrate and back into your bloodstream. This process is known as reabsorption, because this is the second time they have been absorbed; the first time being when they were absorbed into the bloodstream from the digestive tract after a meal.
Detailed explanation-2: -Tubular secretion-The filtrate absorbed in the glomerulus flows through the renal tubule, where nutrients and water are reabsorbed into capillaries. At the same time, waste ions and hydrogen ions pass from the capillaries into the renal tubule. This process is called secretion.
Detailed explanation-3: -What is the overall purpose of tubular reabsorption, the second stage of urine formation? Small molecules, such as water and salts, are removed from the blood. The body gets rid of chemicals and ions that are no longer needed.
Detailed explanation-4: -Hydrogen, creatinine, and drugs are removed from the blood and into the collecting duct through the peritubular capillary network.
Detailed explanation-5: -Urine formation takes place in three steps namely, glomerular filtration, selective reabsorption and tubular secretion. In the first step, blood containing nitrogenous wastes is filtered through a tuft of capillaries called glomerulus. This is followed by selective reabsorption of glucose, amino acids etc.
