A. Polar
The phosphate heads of the phospholipid bilayer are polar, while the fatty acid tails are nonpolar. This amphipathic nature is what allows phospholipids to form a bilayer in aqueous environments, with the polar heads facing outward towards the water and the nonpolar tails facing inward, away from the water.
