Formation of a lipid bilayer is energetically favorable. how does this arrangement result in higher entropy for the system, and thus make bilayer formation energetically favorable? select one:

a. fatty acid tails are highly saturated and flexible.

b. hydrogen bonds form between neighboring polar head groups in the bilayer.

c. polar head groups form a hydrogen-bonding network at the interface with water.

d. water molecules form cagelike structures around hydrophobic molecules.
