What Makes Phospholipids Good at Forming Cellular Membranes

What makes phospholipids good at forming cellular membranes?

A) Regions of aliphatic and hydrophilic atoms causing an internalization of phosphorous making a bilayer.
B) The polar and non-polar regions create an amphipathic bilayer of phospholipids.
C) Covalent and ionic bonds between glycerols create a tight seal around the cell.
D) The three saturated fatty tails in phospholipids create a semi solid like structure that maintains a cell's shape.
