Why do water drops bead on a freshly waxed surface?
 
  A) The wax, which is nonpolar, pushes the water into a bead shape.
  B) The strong cohesive forces between water molecules attract each other and the result is a sphere, which is squashed down into a bead by the force of gravity.
  C) Water's cohesive forces between molecules results in a spherical shape and prevents the water droplet from spreading out evenly over the wax.
  D) A freshly waxed surface carries a small electrical charge, which repel the outer electrons on the water molecules.
