Cell membrane questions

Which intermolecular process primarily drives the formation of a bilayer when phospholipids are added to water?

(Choice A)
Lipids cause water to arrange in an ordered, unfavorable cage-like structure. Forcing lipids into a bilayer reduces this effect.
(Choice B)
Phospholipids self-assemble into a bilayer due to the strong affinity they have for each other.
(Choice C)
The ordered arrangement of a bilayer is more favorable than the disordered state of individual free-floating phospholipids.
(Choice D)
A bilayer arrangement maximizes the strength of Van der Waals forces among phospholipids.
