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 amplitude of a wave function at a particular point in space equals the probability density of finding the electron at that point.
D) Wave functions can have nodes, which are points where the amplitude is zero.
E) Statements A-D are all correct.
