Answer

Brief Explanations:

Reabsorption in the kidneys involves taking useful substances (like glucose, amino acids, water, and ions) from the filtrate (formed after filtration in the glomerulus) and moving them back into the bloodstream. This is a key part of urine formation. The first option describes excretion (not reabsorption). The second option is too broad (urine production has multiple steps - filtration, reabsorption, secretion). The fourth option is filtration (substances from blood to filtrate). The fifth option is incorrect as reabsorption is of useful, not useless, substances.

Answer:

The movement of useful substances from the filtrate back into the blood
