Why Do Water Drops Bead on a Freshly Waxed Surface

Multiple Choice

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.
