Which of the following characteristics would likely enhance the specificity of this drug?

• A) The relative hydrophobicity of the drug molecule.
• B) Phospholipid composition of lung cell plasma membranes.
• C) Specificity of the drug molecule for binding to the extracellular matrix of lung cells.
• D) Similarity of the drug molecule to other molecules normally transported in lung cells.
