The tubular fluid is isotonic as it enters Bowman's capsule and remains isotonic at the beginning of the loop of Henle. It becomes hypertonic at the tip of the loop where water is reabsorbed by the vasa recta, and becomes hypotonic as it leaves the loop to enter the distal tubule where more solutes are reabsorbed. Option A, B, and D do not correctly reflect the change in solute concentration along the different segments of the nephron.
