OPTIONS

(B) Biliary
(C) Pulmonary

Large polar molecules are poorly filtered through the glomerulus and are preferentially eliminated into bile when hepatic transport permits. Renal excretion favors smaller, water-soluble molecules, while pulmonary excretion is mainly relevant to volatile substances and gases.
