The correct answer is: **a. hydrophobic lipid and hydrophilic phosphate**.
The cell/plasma membrane is primarily composed of a phospholipid bilayer, where the hydrophobic (water-repelling) lipid tails face inward, and the hydrophilic (water-attracting) phosphate heads face outward, towards the intracellular and extracellular environments.
