Which of the following statements is true The energy levels

Which of the following statements is true? The energy levels of a one dimensional box are nondegenerate. Two and three dimensional boxes can have degenerate energy levels only if the lengths along the x and y or x. y, and z directions are the same. Two and three dimensional boxes can have degenerate energy levels if any of the quantities are equal The energy levels of a square two dimensional box are nondegenerate.

Solution

B and C
