B)ADH decreases the sodium transporters in the apical plasma membranes lining the DCT and collecting ducts.
C)ADH increases the aquaporins in the apical plasma membranes lining the DCT and collecting ducts.
D)ADH decreases the aquaporins in the apical plasma membranes lining the DCT and collecting ducts.
E)ADH increases both sodium transporters and aquaporins in the apical plasma membranes lining the DCT and collecting ducts.

ADH increases the insertion of aquaporins into the apical plasma membranes of DCT and collecting ducts. This results in increased water reabsorption from the filtrate in the tubules, which leads to water conservation by the body. It does not directly affect the sodium transporters.
