14. A particle is confined in a one-dimensional box with a finite length. The potential energies inside and outside the box are equal to zero and infinity, respectively. From the viewpoint of quantum mechanics, which of the following statement is wrong?
(A). The degeneracy of each energy level is one.
(B). The zero-point energy is equal to zero.
(C). The wavefunction with a higher total energy has a larger number of nodes.
(D). Outside the box, the value of the wavefunction is equal to zero.
(E). The total energy is inversely proportional to the square of the length of the box. (- h2 d22m dx2 +kx²) = Eψ, where x is
