Placing phospholipids into an aqueous solution immediately results in their forming a lipid bilayer. What is the driving force causing this ordered arrangement?

A.	The phospholipids are very ordered in water, and gain freedom of movement by forming a bilayer.
B.	Water, when associated with lipids, is forced into an ordered arrangement with fewer hydrogen bonds. Forcing lipids into a bilayer gains freedom of movement for the water.
C.	Phospholipids have a strong affinity for other phospholipids, leading to self assembly.
