Original PrepAtlas question. This is not an official College Board question.

Methane molecules have no permanent molecular dipole. Which model explains an attractive interaction between two CH4 molecules?

AA permanent positive charge on one methane ion attracts a permanent negative charge on another.BEach methane molecule permanently aligns a C–H bond dipole with the net dipole of its neighbor.CA fluctuation in one electron cloud creates a temporary dipole that induces a correlated dipole in a neighboring molecule.DDispersion attraction can occur only after a nearby ion permanently polarizes each methane molecule.
