Answer: Option B) directly through the lipid bilayer.
Explanation:
Since membrane are made up of a phospholipid bilayer, with hydrophobic heads and hydrophilic tails, it permits the movement of nonpolar (organic) molecules to diffuse through it into the biological membrane. This is because they are lipophilic (lipid-loving) substances.
Examples of molecules that passed directly through the lipid bilayer are pollutants such as poly-aromatic hydrocarbons, benzopyrene etc.
