filtration

secretion

reabsorption

A and B

B and C

A and C

All of the above

Answer 1

An increase in reabsorption of a molecule by the nephron will result in a decreased excretion of that molecule.

Answer - C. Reabsorption

Reabsorption is a process where the molecules are absorbed into the bloodstream from renal tubules which decreases the excretion of that molecule.

Filtration and secretion are increases the excretion of a molecule because secretion of a molecule in the kidney means the movement of that molecule from the bloodstream to renal tubules in the glomerulus and filtration means the movement of that molecule from blood capillaries to renal tubules.
