The nonpolar regions of many biological macromolecules are buried in the interior of the molecule. The driving force for this clustering of nonpolar regions is:
 a. that the relatively strong hydrogen bonding forces between water molecules tend to exclude nonpolar materials from the aqueous environment
  b. that the nonpolar regions recognize similar nonpolar regions elsewhere in the molecule, and they interact through structural complementarity
  c. because the nonpolar regions form a cage-like structure around the charged portions of the molecule
  d. The nonpolar regions are always associated with the DNA genetic material on the inside of the molecule.
