The correct answer is: two quantum mechanical spin states which have no classical analogues
The quantum numbers $+\frac{1}{2}$ and $-\frac{1}{2}$ indicate the rotation of electrons around its axis in opposite directions. Hence, they represent the two quantum mechanical spin states which have no classical analogues.
