e) both [b] and [c]

Explanation:

Tubular reabsorption takes place mainly in the proximal convoluted tubule of the nephron. It is the process by which the nephron removes water and solutes from the tubular fluid and returns them to the circulating blood. The tubular fluid contains the liquid meant to be passed out as urine.

It involves the movement of a substance from the tubular fluid into the peritubular capillary blood. It is considered to be active if any one of the steps of transepithelial transport is active.
