Final Answer :
A
Explanation :
The countercurrent mechanism, which involves the countercurrent multiplier and countercurrent exchange systems primarily in the loop of Henle and the vasa recta of the kidneys, is responsible for concentrating urine. This mechanism allows for the efficient reabsorption of water and solutes, leading to the production of concentrated urine.
