Phospholipids Spontaneously Form a Bilayer in an Aqueous Solution

Phospholipids spontaneously form a bilayer in an aqueous solution. Why do the heads of the phospholipids point out and the tails point toward one another?

A) The tails are nonpolar and form hydrogen bonds with one another.
B) The heads are repelled by the water inside and outside the cell.
C) The tails are repelled by the aqueous environment, and the heads will directly interact with the aqueous solution.
