Answer:
b. phospholipid bilayer of membrane
Explanation:
The phospholipid bilayer evidently has in its structure mainly phospholipids, alcohol compounds and fatty acids.
Each molecule in the membrane phospholipid bilayer has two heads and a tail, both heads being hydrophilic (having affinity for water) and the tail being hydrophobic (having no affinity for water, and therefore repelling it).
This structure, with the heads, which are hydrophilic facing the intracellular and extracellular environments of cells, thus prevents the passage of polar compounds.
