Explanation:
The false statement is C. According to the Heisenburg uncertainty principle, which inspired the modern 'Electron Cloud' model of the atom, it is nearly impossible to predict an electron's path around the atom. The model statement C is referring to is the Neils Bohr model of the atom, which is useful, but inaccurate.
