Which Statement A-D About the Wave Function for a Single $\lambda$

Which statement A-D about the wave function for a single electron is not correct?

A) A French graduate student named Louis de Broglie first had the idea that an electron should be described as a wave
B) Louis de Broglie postulated that the wavelength of an electron is given in terms of Planck's constant and its momentum, $\lambda$ = h/p.
C) The square of the amplitude of the wave function at a particular point in space gives the probability density of finding the electron at that point.
D) An electronic wave function can never be 0 because that would mean the electron does not exist.
E) Statements A-D are all correct.
